Dear Valued Customer,

Congratulations on your recent purchase of a Cemarline Patient Radiation Therapy Laser Alignment

System!

This product is the result of years of continuous quality improvement of laser technologies. If, after

carefully reading this manual, you have any questions, please contact your distributor or our Customer

Service department.

1 Introduction

This Installation and User’s Guide includes all the information you need to safely and

efficiently install, operate and maintain your Laser Alignment System. This guide is only

intended for use with Cemarline MAXX-700 Remote Positioning Lasers, models MAXX-700-

CHG (Crosshair) and MAXX-701-SAG (Sagittal (straight line)).

1.1 Intended Use

These lasers are intended to be used for aligning patients to medical diagnostic imaging

and radiation therapy equipment which utilizes ionizing radiation. They are intended to be

used in medical clinic or hospital settings by trained medical staff. The lasers are not

designed to be used around flammable anesthetics, which present a risk of explosion or fire.

The lasers are not intended to be used in a corrosive environment. No other uses are

intended or implied.

1.2 Safety

Signal words are used according to international standards. The meanings of these signal

words are:

• DANGER - Indicates an imminently hazardous situation which, if not avoided, will

result in death or serious injury. This signal word is to be limited to the most

extreme situations.

• WARNING - Indicates a potentially hazardous situation which, if not avoided, could

result in death or serious injury.

• CAUTION - Indicates a potentially hazardous situation which, if not avoided, may

result in minor or moderate injury. It may also be used to alert against unsafe

practices. Permitted for property damage only accidents.

1.2.1 Laser Safety

WARNING - Risk of incorrect diagnosis or treatment. Isocenter of alignment lasers must

coincide with isocenter of diagnostic or treatment equipment. Testing the alignment of

lasers to isocenter of diagnostic or treatment equipment is based on hospital procedures.


Newly installed equipment can possibly shift as building walls and floor settle and as

building materials dry out. Realign lasers to isocenter before use, if they have moved.

CAUTION - Laser light, risk of eye damage.

- To prevent eye damage, do not stare into laser beam and do not allow patients to

stare into laser beam. The normal blink reflex will prevent eye damage. If a patient

is unable to blink normally the laser operator must prevent laser from shining in

patient's eye. Laser is a class II laser.

- Replace laser diode only with assembly provided by Cemarline to ensure that laser

power levels do not exceed class II limits.

D. The network status LED is solid green to signal good connection from the unit to the remote control. It starts blinking if the laser unit detects the connection is lost.


3 Remote Control Operation

Figure 3-1 Main page

The Main page (Figure 3-1) is the entry point to all the

operations on the remote control.

The remote control and all the laser units in the same

room share a network ID. If multiple rooms are

equipped with MAXX-700 Laser Systems, each room

has a unique network ID. The network ID of each

remote control is displayed at the bottom of the

screen. For example, the remote control shown in

Figure 3-1 has a network ID of 10.

There are three categories of operations: laser unit operations, alignment verification and

remote control settings.

- Laser unit operations

The remote control must link to a laser unit via wireless communication protocol

(Zigbee) before sending any commands to it. Please refer to Section 3.2 on Page 17 to

learn how to use the remote control to link to a unit and perform various operations on

it.

- Alignment verification

If Unit #1 and Unit #2 are properly installed and aligned, you can use alignment

verification to check whether the two units are aligned, as a daily routine, and re-align

them automatically. Please refer to Section 3.3 on Page 31 for more details.

- Remote control settings

You may also check status and update various configurations of the remote control itself.

Section 3.4 on Page 37 provides more details in this group.


3.1 General use of remote control

There are some common elements in multiple pages.

Name Icons and Descriptions

Navigation icons

Located at the upper left corner of the screen, they help users to quickly navigate

to certain pages.

- Go to the previous page.

- Go to the next page, available on laser line positioning pages.

- Go to the parent page.

Unit number box

Appears at the upper right corner of the screen if there is no status bar on the page,

or adjacent to status bar if there is one. It displays the current laser unit number.

- The current unit is Unit #1.

Status bar

Appears at the upper right corner of the screen and indicates status of operation.

- The remote control and the laser units are idle. You may start any operation

available by clicking the corresponding icon on the screen.

- The designated operation is in process.

IMPORTANT: please DO NOT touch the screen while the remote is in

this state. If it lingers in this state much longer than the estimated time,

please restart the remote control. You can find the estimated time for each

laser-involved operation in paragraphs starting with .

- The designated operation has been successfully completed.

- The designated operation has failed or there has been communication

problem. You may repeat the previous operation or check the communication.

Please refer to Section 5.1 “Operation Failure” on Page 47 for details on

troubleshooting.


3.2 Laser unit operations

3.2.1 Linking and status checking

Before operating any laser unit, the remote control must check communication and other

status of laser units.

Figure 3-2 Checking status of laser units

Click the Link icon on the Main page, and the remote

control will try to link to each unit with the same PAN ID in

the Zigbee network.

As shown in Figure 3-2, an hourglass image appears above

the Link icon, indicating that linking and status checking is in

process. When the process is finished, the remote control

opens the Unit Selection page (Figure 3-3).

The remote control retrieves the following information from laser units:

- Wireless connection status of each unit

- Laser power status of each unit

- Alignment tolerance setting of Unit #1 and Unit #2

Upon receiving the above information, the remote control updates status of UI controls on

relevant pages.

For every unit linked to the remote control, the time to finish linking and status

checking increases by about one second. There are four laser units in a fully installed

MAXX-700 Hospital Laser System. If all four units are installed and powered on in the

room, it takes about four seconds to complete the communication and status checking

procedure. Longer delay indicates some units cannot be properly linked.

3.2.1.1 Unit Status

Figure 3-3 shows the Unit Selection page when all the regular units are connected and all the

lasers are beaming. The number on the Unit Selection icon matches the unit number

displayed on the front of the corresponding unit.

Note: Unit #5 is the spare unit available with each system. Please refer to Section 4 “Spare

Unit” on Page 43 for details regarding the installation and usage of Unit #5.


Figure 3-3 Unit Selection page

Figure 3-4 shows that Unit Selection icons can show different states of network connection

and room configuration of the corresponding unit.

Figure 3-4 Unit Selection icons show different

states of units

The background color of the icon indicates whether the unit is

linked.

: The corresponding unit is linked. The icon is enabled and can

be clicked.

: The corresponding unit is not linked. The icon is disabled

and cannot be clicked.

: The corresponding unit is configured off by Room

Configuration function, and it does not accept any commands from

the remote control. Please refer to Section 3.4.4 “Room

Configuration” on Page 41 for details.

3.2.1.2 Laser Power Status and Laser Power Switches

Other than unit status, the Unit Selection page also shows laser power status of each

linked unit via Laser Power Indicator in front of the corresponding Unit Selection icon.

- : Laser is beaming on this unit.

- : Laser is turned off on this unit.

It is possible to turn on or off laser power on all linked units at the same time, instead of

changing their power status one by one. Instructions accompanying Figure 3-5 and Figure 3-6

provide more details.

See Section 3.2.1.2.

Laser power switches

See Section 3.2.1.2.


Figure 3-5 Laser power switches

: Power-off All Lasers icon - To switch off laser power on

ALL the linked units. Available if at least one unit has its laser

power on.

: Power-on All Lasers icon - To switch on laser power on

ALL the linked units. Available if at least one unit has its laser

power off.

In Figure 3-5, lasers on Unit #1 and Unit #2 are beaming, while

the other two lasers are not. In this case, you may turn on all

lasers by clicking , or turn off all lasers by clicking .

Figure 3-6 All laser beams are turned off

Figure 3-6 shows the Unit Selection page when all laser beams

are turned off. The status bar becomes green when the remote

control receives positive replies from all linked units.

If you need to adjust laser power individually, please refer to

Section 0 on Page 21.

The time needed to process laser power switching commands depends on the number of

linked units. Generally, it increases by one second per unit. If all four units are linked, it

takes within four seconds to complete the laser power switching operation. The status bar

becomes red if the remote control fails to receive positive reply from any of the linked units

within five seconds.

3.2.1.3 Unit Selection

Click an enabled Unit Selection icon to select the corresponding unit. The remote control

will open the Function Selection page (Figure 3-7) immediately. Now you can send control

commands to the selected unit.

The recommended order of unit operation is: 1->2->3->4, if applicable.


3.2.2 Function Selection

The Function Selection page (Figure 3-7) is the entry point to all the laser control functions,

except alignment checking and re-alignment function.

There are five function icons available for all the units on the Function Selection page.

Alignment settings function is only available for Unit #1 and Unit #2 when both units are

connected to the remote control.

Figure 3-7 Function Selection page for Unit #1 and Unit #2

: Laser power adjustment (Section 3.2.2.1, Page 21)

: Focus adjustment (Section 3.2.2.2, Page 22)

: Factory settings (Section 3.2.2.3, Page 23)

: Line positioning – continuous (Section 3.2.2.4.1, Page 27)

: Line positioning – stepping (Section 3.2.2.4.2, Page 27)

: Alignment settings (Section 3.2.2.5, Page 28)

There are also two navigation icons on the Function Selection page.

- Go to the Main page (Figure 3-1, Page 15) directly. This provides a quick jump to

other functions of remote control.

- Update unit status and go to the Unit Selection page (Figure 3-3) directly. This

ensures that the connection status and laser power status of units are always

updated before the opening the Unit Selection page. Please note that the same

estimated delay for linking and status checking applies here as in Section 3.2.1 on

Page 17.

It is RECOMMENDED to follow the order of the subsequent sections to complete the initial

installation and alignment procedure.


3.2.2.1 Laser Power Adjustment

The first step of initial system setup is to use this function to adjust the laser brightness to

the desired level.

Figure 3-8 Laser Power Adjustment page

: Power-down icon – to lower laser brightness

: Power-up icon – to increase laser brightness

: Power-off icon – to turn off laser beam of the current unit

The current level of laser beam power is displayed in the power

grid at the bottom of Laser Power Adjustment page. The number of

green cells in the power grid corresponds to the power level. For

example, the power level of Unit #1 is 5 in Figure 3-8.

Figure 3-9 Laser power has been increased

Figure 3-9 shows the result of one click on power-up icon ( ).

The command has been completed without problems( ) and

the power grid shows six green cells, indicating power level has

been increased to six now. If the current power level reaches the

upper limit(12), the Power-up icon will be hidden.

Similarly, the Power-down icon( ) will lower the laser power

level. If the current power level reaches the lower limit (1), the

Power-down icon will be hidden.

Intelligent ambient light sensing

The laser power level is saved at the processor board inside the laser unit automatically

while being adjusted and will be applied accordingly when ambient light changes are

detected by the laser unit. If the ambient light becomes brighter or darker, the laser

power will be increased or decreased automatically according to the previously saved

power setting. The laser power settings are persistent at power cycle.

Please note that the same power level setting may result in slightly different levels of laser

brightness on different laser modules.

Sometimes the alignment procedure requires one or more laser beams to be turned off

individually. This can be achieved by using Power-on ( ) and Power-off ( ) icons.

If the laser is currently beaming, the Power-off icon and power level adjustment icons are

available, as shown in Figure 3-8.

Click Power-off icon to turn off the laser, and the power level adjustment icons will be

hidden and Power-off icon will become Power-on icon as shown in Figure 3-10.


Figure 3-10 Laser Power has been turned off

: Power-on icon – to turn on laser beam of this unit

Click Power-on icon to turn on laser beam, and the remote

control screen will return to Figure 3-8.

A single laser power adjustment operation or laser power switch operation normally

finishes within three seconds.

3.2.2.2 Line Focus Adjustment

The laser beam should be finely focused before laser line position is adjusted. The functions

provided on this page enable fast and fine focus adjustments.

Figure 3-11 Focus adjustment page

: Stepping movement of focus motor. The motor moves

one step at each click on the corresponding icon. Please note that

there will be no motor movement if you click the stepping icons

more than twice in a second.

: Continuous movement of focus motor. The motor starts

moving continuously once the corresponding icon is pressed and

stops moving when the icon is released. Please note that there will

be no motor movement if you tap on the continuous icons quickly.

It is RECOMMENDED to use continuous focus adjustment functions to reduce laser line

thickness rapidly until the thinnest point has passed. Then use stepping adjustment in

reverse direction to reach the thinnest point.

A single stepping operation should be completed within two seconds. For the continuous

operation, there is a one-second delay from the moment you press the icon to the moment

the motor actually starts to move. Similarly, there is a one-second delay from the moment

you release the icon to the moment when the motor actually stops moving and another one-

second delay until the remote control receives the feedback from the laser. Due to the

nature of wireless communication, occasionally you may observe slightly greater than

typical delays stated above. You may assume that communication is unstable if any of the

delays are longer than five seconds.


These typical delays also apply to Laser Line Positioning commands introduced in Section

3.2.2.4 “Laser Line Positioning” on Page 24.

3.2.2.3 Factory Settings

At any time, you can use this function to bring a selected motor back to its factory setting

position, which is the mechanical center. This operation is also called homing.

It is RECOMMENDED to home all motors applicable before installation and alignment of

MAXX-700 system.

Homing is applicable to horizontal motor, vertical motor, roll motor, and pitch motor on

MAXX-700-CHG (Crosshair) units, as shown in Figure 3-12, and to horizontal motor and roll

motor on MAXX-701-SAG (Sagittal) units, as shown in Figure 3-13.

Figure 3-12 Factory Settings page - crosshair

Horizontal Motor Homing icon

Vertical Motor Homing icon

Roll Motor Homing icon

Pitch Motor Homing icon

Units #1, #2, and #3 are crosshair units.

Figure 3-13 Factory Settings page - sagittal

A sagittal unit only generates a vertical straight line, so there is no

vertical motor or pitch motor on the unit.

Unit #4 is always a sagittal unit.

Click one of the Homing icons available to send Homing command to the selected unit.

Figure 3-14 shows the screenshot of remote control while the horizontal motor of Unit #1 is

being homed.


Figure 3-14 Horizontal motor is being homed

In addition to the status bar being yellow, the “Homing in process”

picture label in front of the selected Homing icon indicates that

this motor is currently moving to its mechanical center position.

Figure 3-15 Horizontal Motor is homed

Once the motor is successfully homed, the “Homing done” picture

label appears in front of the selected Homing icon (Figure

3-15). And the status bar becomes green.

Depending on the motor’s position before being homed, this operation may take from 2

seconds to 45 seconds to complete. The status bar becomes red, this signals a timeout if the

remote control does not receive homing result within 45 seconds. In this situation you may

check link status and repeat the operation.

If the laser line position is adjusted by other commands on other pages, the “Homing done”

picture label will be removed from the front of the corresponding Homing icon.

Please note that the homing status is not persistent at power cycle, i.e., the remote control

always assumes it has no knowledge of homing status of any laser unit at power up.

3.2.2.4 Laser Line Positioning

Similar to laser focus adjusting functions, there are two groups of laser line positioning

functions: continuous movements and stepping movements .

It is RECOMMENDED to use continuous movement functions to move laser lines as close

as possible to the desired position. Then use stepping movement functions to accurately

position the laser lines.

All the moving directions are from the point of view of a beaming laser. The operators

should look at the laser cross beamed by a MAXX-700-CHG (Crosshair) unit or the straight


line beamed by a MAXX-701-SAG (Sagittal) unit on the laser’s side. Please refer to Table 3-1

if you need more information on the laser line positioning functions. For MAXX-701-SAG

units, please ignore all the horizontal line-related illustrations in the table.

There are two motors available for horizontal line positioning: vertical motor and pitch

motor. Generally the operators should use the pitch motor functions to quickly move the

horizontal line to the proximity of destination, and then use vertical motor functions to

accurately position the horizontal line.

Similarly you may use either horizontal motor or roll motor to position the vertical line. The

roll motor functions enable quick movement of the vertical line towards the proximity of

destination. And the horizontal motor functions can be used to accurately move the line to

its final position.

Beam rotation motor functions are used to align two facing laser beams or to align one laser

beam to a given reference line.

Please refer to Section 3.2.2.2 “Line Focus Adjustment” on Page 22 for more information

on typical delays for stepping movement commands and continuous movement commands.

the motor is moving.

Release the icon, and the motor stops moving almost immediately.

The status bar turns green, indicating the motor has stopped

moving.

If the status bar becomes red before the icon is released, the

transmission of “Start moving” command has failed. If the status

bar becomes red after the icon is released, the transmission of

“Stop moving” command or feedback from laser has failed.

Click a Stepping Movement icon, and the selected motor moves

towards the designated direction one step at a time.

The status bar becomes yellow while remote control is waiting for

feedback from laser. It becomes green when positive feedback is

received. It becomes red when negative feedback is received or the

operation has timed out.

For horizontal and vertical motors, the selected motor drives

corresponding laser line to move a distance in the range of 0.1 to

0.3 millimeters per step, depending on selection of motor and

direction.

3.2.2.5 Alignment Settings

If Unit #1 and Unit #2 are properly installed and aligned to each other, you can save the

current positions of laser lines and use them in Alignment Verification Function (Section

3.2 , Page 31).

There are two ways to open the Alignment Settings page (Figure 3-20).

- Click Alignment Settings icon on Function Selection page (Figure 3-7, Page 20);

- Click Alignment Settings icon on Alignment Verification page (Figure 3-26,

Page32).

On both of the above pages, the Alignment Settings icon is only available when unit #1

and unit #2 are both connected and beaming.

3.2.2.5.1 Alignment Tolerance Levels

Alignment tolerance range refers to a small range close to the saved center position on the

sensor. It determines the accuracy of alignment checking and re-alignment.

We define the saved center position as zero position. The alignment checking and re-

alignment procedure will check how much the laser line is off from the zero position. If it is

out of the tolerance range, the laser line is misaligned. Otherwise, it is regarded as aligned,

even if the laser line is several pixels off the zero position.

There are four alignment tolerance levels defined for alignment checking and re-alignment

of Unit #1 and Unit #2. The tolerance range values and the corresponding icons are given in

Table 3-2.

It is the user’s decision to select a proper tolerance level. It takes longer to re-align the

units if the tolerance level is smaller, but the alignment checking and re-alignment result

will be more accurate.


Table 3-2 Alignment tolerance levels

Tolerance level Alignment accuracy Tolerance value (pixels) Tolerance value (mm)

TL1 ± 0.1 mm 7 0.1

TL2 ± 0.2 mm 14 0.2

TL3 ± 0.4 mm 28 0.4

TL4 ± 0.8 mm 56 0.8

Please follow the instructions below to verify and set up the desired tolerance level.

Figure 3-20 Alignment Settings page

: Tolerance Level Selection icons

The tolerance value of the selected tolerance level is shown

between the two Tolerance Level Selection icons. In Figure 3-20,

the tolerance value is 0.2 mm.

If Unit #1 and Unit #2 do not have the same tolerance level setting,

no tolerance level icon will be highlighted.

Figure 3-21 Tolerance level is changed

Click to select a smaller tolerance value, or click to

select a larger tolerance value. In Figure 3-21, TL1 is selected.

The “Save changes” icon only appears if the new tolerance

level is different from the current level.

Click to save the new tolerance level to BOTH units. As usual,

a successful save results in a green status bar.

It usually takes about three seconds from the moment when the “Save changes” icon is

clicked to the moment when a positive reply is received at remote control and the status bar

becomes green. The status bar turns red if the remote control has failed to send the

command, or has not received reply from the laser within five seconds, or has received a

negative reply.

3.2.2.5.2 Saving center positions

The ambient light in the room must be dimmed for all the operations in this section, in

order to ensure the correctness of center position saving and alignment verification later.

Also make sure that no laser lines are reflected onto the sensor windows of Unit #1 and

Unit #2.


Since Unit #1 and Unit #2 store the center position for each other, please make sure that

the laser lines from Unit # 1 beam inside the sensor windows on Unit #2, and vice versa.

Figure 3-22 Ready to save centers

- Save Centers: save current horizontal and vertical positions

of the other unit as center positions

Once the laser positions and tolerance level settings have been

verified, click the Save centers icon to save the current

positions as the center positions.

This operation sends “Save centers” command to BOTH Unit #1

and Unit #2. As usual, a successful save results in a green status

bar.

It usually takes about three seconds from the moment the “Save centers” icon is clicked

to a positive reply is received at remote control and the status bar becomes green. The

status bar turns red if the remote control has failed to send the command, or has not

received reply from the laser within five seconds, or has received a negative reply.

3.2.2.5.3 Fast navigation to other pages

The remote control can navigate to other relevant pages directly from Alignment Settings

page (Figure 3-20).

- Go to Function Selection page (Figure 3-7, Page 20) of Unit #1 or Unit #2, if

you need to do more laser line positioning adjustment on these two units. This

provides a fast switch to the adjustment functions of Unit #1 and Unit #2.

- Go to Alignment Verification page (Figure 3-26, on Page 32), if you need to check

alignment status.


3.3 Alignment Verification

This function can be used as a daily routine to verify if Unit #1 and Unit #2 are vertically

and horizontally aligned after the initial installation and alignment have been completed.

Figure 3-23 Opening Alignment Verification

page

Click the Alignment Verification icon on the Main page,

and the remote control will check status of Unit #1 and Unit #2.

As shown in Figure 3-23, an hourglass image appears above the

Alignment Verification icon, indicating that linking and status

checking on Unit#1 and Unit #2 is in process.

If both units are linked and beaming, the remote control opens the

Alignment Verification page (Figure 3-26). Please read Section

3.3.1 for instruction on how to perform alignment verification.

Figure 3-24 Alignment verification disabled -

case 1

Figure 3-24 and Figure 3-25 illustrates two cases when

alignment verification function is disabled.

In the case of Figure 3-24, the Alignment Verification icon is

disabled because Unit #2 is not linked and the alignment

verification cannot be done.

Figure 3-25 Alignment verification disabled -

case 2

In the case of Figure 3-25, the Alignment Verification icon is

disabled because the laser on Unit #1 is not beaming and the

alignment verification cannot be done.

The status checking procedure should be completed in about two seconds.

3.3.1 Alignment checking

IMPORTATNT: during the entire procedure of alignment verification and re-alignment, the

room lights must be dimmed to the same level as when the center positions are saved. Also

make sure that no laser lines are reflected onto the sensor windows of Unit #1 and Unit #2.


Figure 3-26 Alignment Verification page

Click the Check Alignment icon on the Alignment

Verification page (Figure 3-26) to send “Check Alignment”

command to both units at the same time. The status bar will be

yellow while the operation is in process.

The alignment checking procedure should be finished within three seconds.

3.3.2 Alignment checking results

When the remote control successfully receives feedback from the units, the Alignment

Verification page shows the checking results.

Table 3-3 summarizes the information presented on the Alignment Verification page as

result of “Check Alignment” command.

Some notes on offset values in Offset Boxes:

• The offset values are displayed in the format of

<Offset value> / <Tolerance value>,

Where <Tolerance value> is determined by tolerance level set up in Alignment

Settings page. Please refer to Section 3.2.2.5.1 on Page 28.

• The displayed offset values are a close estimate of how much the laser beams are

deviated from the saved positions measured at the sensor windows.

• Offset values are available in two measurement units: in pixels or in millimeters.

• Each pixel equals 14 micrometers.

• The two measurements can be easily converted to each other by clicking the Convert

Measurement Icon ( ) on top of the Alignment Verification page. In Figure 3-27, all

offset values are displayed in pixels. After conversion, all offset values are displayed

in millimeters, as shown in Figure 3-28.

Figure 3-27 Offset values in pixels

Figure 3-28 Offset values in millimeters

Please note that pixel values are more precise than millimeter values, as those

numbers are direct readings from sensors while millimeter values are calculated

from the pixel values. However, millimeter values provide a more straightforward

idea on how big the offsets are. In any case, the computational difference is

negligible.

Figure 3-29, Figure 3-30, and Figure 3-31 show three cases of possible results of alignment

checking.


Case 1 The horizontal and vertical lines from both Unit #1 and Unit #2 are aligned.

Figure 3-29 Alignment verification - both units are

aligned

All offsets are displayed in green.

The “Alignment Done” image is in place of the Alignment

Verification icon at the center of the page.

There is no need of further actions on this page.

Case 2 At least one of the two units is misaligned, i.e. at least one laser line is not at

center.

Figure 3-30 Alignment verification - Unit #1 is out

of alignment

- Auto-alignment icon, disabled

The unit number on the icon of the misaligned unit becomes red,

as on Unit #1 icon in Figure 3-30.

The Offset Box displays <offset value>/<tolerance value> in red.

The Auto-alignment icon is shown at the center of the page but it

is disabled because no unit is selected yet.

In this case, please refer to Section 3.3.3 on Page 35 for

instructions on how to start auto-alignment procedure.

Case 3 The alignment verification has failed.

Figure 3-31 Alignment verification has failed

The status bar is red in this case.

You may check the communication status and do the alignment

checking again.


3.3.3 Automatic re-alignment

Click one of the unit icons to select the unit to be re-aligned. Figure 3-32 and Figure 3-33 show

the procedure of re-alignment one unit. If there is more than one unit misaligned, re-align

one unit after another. The two units cannot be re-aligned at the same time.

Figure 3-32 Unit #1 is to be aligned

: Auto-alignment icon, enabled

In Figure 3-32, Unit #1 is selected, and the background color of

the icon has been darkened. Now the Auto-alignment icon is

enabled. Click it to start automatic re-aligning operation.

The two units communicate to each other directly during auto-

alignment. In the example of Figure 3-32, Unit #2 repeatedly

checks laser line positions for Unit #1 and instructs Unit #1 to

move the lines back to centers. When the offsets are within

tolerance range, Unit #2 reports to the remote control that Unit #1

has been aligned.

Figure 3-33 Unit #1 has been re-aligned

The remote control updates the offsets and paints status bar green

(Figure 3-33), if the operation is successful. The “Alignment

Done” image is in place of the Alignment Verification icon at the

center of the page.

The re-alignment of Unit #1 is finished.

If the status bar becomes red, the operation has failed. In this

case, you may check communication status of the units. If

connection is OK, start the auto-alignment procedure again.

The time to finish auto-alignment varies from a few seconds to close to one minute,

depending on the initial misalignment offsets. If the remote control does not receive auto-

alignment results in 60 seconds, it reports a timeout by changing status bar to red. If a unit

cannot be aligned in 50 moves, including both fast moves and stepping moves, the other

unit will report timeout to the remote control. In any case, try the auto-alignment process

again.

3.3.4 Fast navigation to other pages

The remote control can navigate to other relevant pages directly from Alignment

Verification page.

- : Go back to the Main page (Figure 3-1 on Page 15).

- : Go to Alignment Settings page (Figure 3-20 on Page 29). This is useful when you

want to change alignment settings before the next alignment checking operation.


Please note that changing alignment settings may result in different alignment

status.

For example, Unit #1 has been aligned with tolerance level TL4 in Figure 3-33. Then

the operator goes to Alignment Settings page and changes the tolerance level to TL1,

as shown in Figure 3-34. Now Unit #1 becomes misaligned again with new tolerance

level, as shown in Figure 3-35. Figure 3-36 shows the result of re-alignment. Obviously,

the unit has been re-aligned with much higher level of accuracy.

3.4 Remote Control Settings

Click the Remote Control Settings icon on the Main page, and the remote control will

open the Remote Control Settings page (Figure 3-37) immediately.

Figure 3-37 Remote Control Settings

Revision of remote control - the latest revision of remote control is 3.3.3. Please make sure

that your remote control and all the documents have the same revision number.

Battery capacity indication - the estimated battery capacity in percentage. Please refer to

Section 3.4.1 “Battery capacity indication” for more information.

Function icons - There are three categories of remote control-oriented settings.

3.4.1 Battery capacity indication

The remote control is a battery-powered hand-held device. It is very important to put your

remote control back to the charger whenever possible to avoid service disruption.

The battery capacity indication on the upper right corner of the Remote Control Settings

page informs users how much capacity is remaining in the battery. Both the battery

capacity percentage and the battery image are updated every 30 seconds.

- : The battery image is filled with green blocks if the capacity is greater

than 25%.

- : The last remaining block turns yellow if the capacity is between 20%

and 25%.

- : The last remaining block turns red if the capacity is below 20%.

In addition, the Low Battery Warning, as shown in Figure 3-38, starts popping up every five

seconds if the battery capacity is below 20%. All the regular operations are not affected as

To Main page

Revision of remote control

Battery capacity indication

Function icons


long as the icons are not blocked by the popup. You may click the Close Popup icon to

dismiss the warning, or wait five seconds until it disappears automatically.

Figure 3-38 Low Battery Warning popup

We strongly suggest that you put the remote control to a charger immediately as soon as

the first Low Battery Warning shows up. If you ignore the warning and continue using the

remote control without charging, the remote control will enter sleep mode automatically as

soon as the remaining capacity is below 15%.

3.4.2 Power saving settings

It is very important to minimize power consumption in order to maximize operation time of

the remote control. We provide two power saving configurations to users: LCD-off timer and

sleep timer. The wake-up methods are different as described below.

Figure 3-39 Power saving settings

LCD-off timer: The screen will be shut off if there is no

activity on remote control after 2 minute by default (Figure 3-39),

or the amount of time set by users (Figure 3-40).

Sleep timer: the remote control will enter sleep mode if there

is no activity on remote control after 15 minutes by default (Figure 3-39), or the amount of time set by users (Figure 3-40).

Wake-up methods

LCD-off - Tapping the touch screen at the top right corner will bring the screen back and

allow users to resume previous operation. Please DO NOT touch anywhere else to wake

up the screen, as you may accidentally hit some control icons causing unwanted laser

movements.

Sleep - Toggling the power switch UPWARDS will wake up the remote control and allow

users to resume previous operation.


Figure 3-40 Power saving settings are changed

If any of the timer settings are changed, the “Save changes” icon

will appear to enable saving changes (Figure 3-40).

Click the icon to save the changes to the remote control. The new

settings take effect immediately.

As usual, the color change of the status bar indicates whether the

operation has been successful or not.

3.4.3 Network ID Configuration

This function allows operators to change PAN ID of the remote control. We strongly

recommend associating one remote control to one set of lasers permanently. However, it is

practical to use one remote control to adjust lasers in multiple rooms in such cases as:

- One of the remote control is dysfunctional, and the operators may temporarily use another

remote control in place of the original one to ensure uninterrupted medical service;

- Some operators prefer to use one remote control to set up and adjust laser units in all the

room to ensure better equipment management;

- Use a single remote control to configure the spare unit.

In any of the above cases, PAN ID of the remote control must be changed before it can be

used to control lasers in the room.

Note: Improper use of this function may cause communication chaos in multiple rooms

equipped with MAXX-700 laser units. This is why this function is password-protected.

Please contact Cemar Electro Inc. Customer Service for more information.

Please follow the steps in the example below to switch PAN ID of a remote control. Assume

the remote control has PAN ID of 10. Now we need to use it in PAN-30 room for some

reason.

Click PAN ID Configuration icon on the Remote Control Settings to page to open

Password page, as shown in Figure 3-41.


Figure 3-41 Password page

Click corresponding digit icons to input password.

: to delete the last digit

: to clear all the inputs

: to enter password

You have three chances to enter the correct password. After three

unsuccessful trials, the remote control will disable this function and

jump back to Remote Control Settings page (Figure 3-37, Page 37)

automatically.

Figure 3-42 PAN Configuration page

If your password is correct, the remote control will open the PAN

Configuration page (Figure 3-42). The current PAN ID of the remote

control is displayed on the page.

Now you may start to set new PAN ID.

Figure 3-43 Set new PAN ID to 30

One click on will increase the PAN ID by 10.

One click on will decrease the PAN ID by 10.

Valid values of PAN ID: 10, 20, 30, 40, 50, 60, 70, 80, 90, A0, B0,

C0, D0, E0, F0. Contact Cemar Electro Inc. if you have more than 15

rooms to be equipped with MAXX-700 laser systems.

Figure 3-44 Saving new PAN ID to remote

control

Click Save Changes icon to start changing PAN ID of the

remote control. Status bar remains yellow ( ) during the

process.

Usually the process finishes within five seconds.


Figure 3-45 New PAN ID is saved

Once PAN ID has been successfully changed, status bar

turns green ( ) and the new PAN ID is displayed, as

shown in Figure 3-45.

Figure 3-46 Main page – PAN-30

You can verify the new PAN ID by going back to the Main

page and checking PAN ID there. Figure 3-46 shows that

the current PAN ID is 30.

Now you can start using this remote control to send

commands to laser units in the new network.

3.4.4 Room Configuration

There are four regular laser units and one spare unit in a fully equipped room. However,

the room configuration can be very flexible. It is common to have less than four MAXX-700

units installed in a room. In that case, room configuration function can be used to set up

which units have been installed. Thus there will be no laser control functions available for

those uninstalled units.

Another potential use of room configuration function is to “lock up” laser positions to

prevent accidental or unauthorized operations on lasers.

The default room configuration is all units being enabled except the space unit (Unit #5).

It is RECOMMENDED to do room configuration after the installation of laser units.

However, the configuration can be performed at any time whenever situation has changed.

Click the Room Configuration icon on the Remote Control Settings page (Figure 3-37)

to open the Room Configuration page (Figure 3-47). Then follow the steps below to change

room configuration.


Figure 3-47 Room Configuration

Each Unit Number icon corresponds to a laser unit with the

unit number on the icon. The icon may be shown in two

background colors:

: The corresponding unit is enabled.

: The corresponding unit is disabled.

As a spare unit, Unit #5 is disabled by default to avoid

confusion, as shown in Figure 3-47.

Figure 3-48 Change configuration

Click the Unit Number icon to toggle the configuration state

of the corresponding unit. Figure 3-48 shows that Unit #3 is

selected to be disabled.

Any change of room configuration will trigger the Save

Changes icon to show up. Click it to save the changes

to the remote control.

Figure 3-49 New configuration has been saved

The Save Changes icon will be hidden once the

changes have been successfully saved, as shown in Figure 3-49.

The changes will be lost if you leave the current page

without saving the changes.

Figure 3-50 Unit Selection - Unit #3 is disabled

The unit that has just been disabled is displayed as a place

holder on the Unit Selection page (Figure 3-50).


4 Spare Unit

One spare unit, Unit #5, is available with MAXX-700 hospital laser system. If one of the

regular laser units (Unit #1, #2, #3, or #4) is dysfunctional, Unit #5 can be used in place of

the dysfunctional unit while it is being repaired or replaced.

Please follow the instructions below carefully to configure, use, and reset the spare unit.

4.1 Configuring Spare Unit

Step 1 Install the spare unit and prepare a PAN-10 remote control.

Install Unit #5 in the place of the dysfunctional unit, following instructions given in Section

2 “Installation” on Page 10.

In addition, you need a PAN-10 remote control to do the configuration because the default

PAN ID of Unit #5 is 10. If the PAN ID of the current remote control is not 10, please follow

instructions in Section 3.4.3 “Network ID Configuration” on Page 39 to switch the PAN ID

to 10.

Step 2 PAN-10 remote control links to the spare unit.

Plug in Unit #5. The network status LED should become solid green within three seconds.

On the PAN-10 remote control, check room configuration and make sure Unit #5 is enabled,

following instructions in Section 3.4.4 on Page 41.

Let the PAN-10 remote control link to Unit #5 (Section 3.2.1, Page17).

Figure 4-1 shows the Function Selection page for Unit #5.

Figure 4-1 Function Selection page for Unit #5

: Network Configuration icon, for Unit #5 only.

Click the Network Configuration icon to open Network

Configuration page (Figure 4-2).


Step 3 Change PAN ID of spare unit

The operation is the same for any valid values of PAN ID. If the dysfunctional unit was in

PAN-10 network, this step can be skipped.

Assume the network ID of the dysfunctional unit is 30.

Figure 4-2 Network Configuration page - Unit #5 on PAN-10 remote control

Increase PAN ID icon in the PAN ID Box: to increase

PAN ID of the unit by 10 on each click.

Decrease PAN ID icon in the PAN ID Box: to

decrease PAN ID of the unit by 10 on each click.

Since 10 is the minimum value of PAN ID, only the Increase

PAN ID icon is shown by default in Figure 4-2. Click

and will appear, as shown in Figure 4-3.

Keep clicking until the new PAN ID is 30.

Figure 4-3 Changing PAN ID of spare unit

The Save Changes icon appears beside the PAN ID box

when the displayed PAN ID does not equal the current PAN

ID of the unit.

Click to send “Change PAN ID” command to Unit #5.

The remote control returns to the Main page (Figure 3-1)

automatically after the command is successfully sent.

Upon receiving the command, the network status LED on

Unit #5 becomes yellow and the unit number LED on Unit

#5 becomes “-”, indicating PAN ID configuration is in

process.

Once the process has finished, the network status LED on

Unit #5 turns solid green and the unit number LED shows

“5”.

The PAN ID changing process should be completed within three seconds. If the network

status LED on Unit #5 does not turn solid green ten seconds after the Save Changes icon is

clicked, please press the RESET button on Unit #5 to reset its network configuration

(Section 4.2 , Page 46). Then repeat operations from Step 2.

Step 4 Change PAN ID of remote control

If the dysfunctional unit was in PAN-10 network, this step can be skipped.

Now that the spare unit is in the network of PAN-30, the remote control needs to be in the

same network to be able to configure its unit number. Please follow instructions in Section

PAN ID Box


3.4.3 “Network ID Configuration” on Page 39 to switch the PAN ID of the remote control to

30.

Step 5 Change unit number of spare unit

Assume the unit number of the dysfunctional unit is 2. The operation is the same for other

valid values of unit number.

Use the PAN-30 remote control to open Network Configuration page for Unit #5. The page

should look like Figure 4-4.

Figure 4-4 Network Configuration page -

PAN30/Unit #5

Decrease Unit Number icon in the Unit Number Box:

to decrease unit number by 1 on each click

Increase Unit Number icon in the Unit Number Box:

to increase unit number by 1 on each click

Since 5 is the maximum value of unit number, only the

Decrease Unit Number icon is shown by default in Figure

4-4. Click and will appear, as shown in Figure 4-5.

Figure 4-5 Changing unit number of spare unit

The Save Changes icon appears beside the Unit

Number Box when the displayed unit number does not

equal the current unit number of the unit.

Click to send “Change Unit Number” command to

Unit #5. The remote control returns to the Main page

(Figure 3-1) automatically after the command is

successfully sent.

Upon receiving the command, the network status LED on

Unit #5 becomes yellow and the unit number LED on Unit

#5 becomes “-”, indicating unit number configuration is in

process.

Once the process has finished, the network status LED on

Unit #5 turns solid green and the unit number LED shows

“2”.

The Unit Number changing process should be completed within five seconds. If the

5 Troubleshooting

5.1 Operation Failure

If any operation cannot be completed successfully, the status bar on the remote control

turns red after timeout. In most of cases, this is due to wireless communication problem.

Please follow instructions in Section 3.2.1 “Linking and Checking Status” on Page 17 to

check if the target unit can be linked. If linking to the unit is successful, you can repeat the

previously failed operation.

If linking fails too, please follow the steps below:

1. Make sure there is no other wireless device in the room;

2. Check the network status LED on the target unit. If it is solid green, simply restart

the unit and try linking it again. If it is blinking, go to next step;

3. Check the network status LED on other laser units in the same room. If all the other

units have solid green LED, simply restart the unit and try linking it again. Otherwise,

go to next step;

4. Shut down all the units and power down the remote control. Wait at least 10 seconds,

then power up the remote control first, followed by the laser units. The network status

LEDs should turn solid green shortly after power-up. Now try linking to each laser unit.

If this fails, call Cemar Electro Inc. Customer Service for more information.
