Congratulations on the purchase of your new XPERT SL 45 !
This instruction manual is designed as a training and reference manual for the
operation and maintenance of the instrument. We recommend that you read it
carefully prior to use and follow the instructions to ensure optimum

LABOMED XPERT SL 45 Slit Lamp is an all-in-one Ophthalmic instrument for
observation, measurement and diagnosis of Contact lens fitting, Anterior eye
segment, Cataract, Glaucoma, Retina etc.
Its ergonomic design also allows the XPERT SL 45 to be used in laser therapy,
this has been achieved by the possibility of operating the Slit projector in the
central position either with the left hand or right hand. The excellent
transmission of the optical system minimizes light loss during therapy.
Together with the excellent image quality, this provides ideal conditions for
crisp, crystal clear images of even the finest structure.
Considering standard work procedures, the design of this system provides you
with an optimum, ergonomically correct configuration.
The perfection of the observation system and outstanding operating
convenience ideally compliment each other. The outstanding benefits of this
design include a short working distance, comfortable arm and body posture,
easy to grip controls for the sensitive setting of the Slit length, width and
rotation. Using with joystick, you can control the XPERT SL 45 quickly and
precisely in all three coordinates and set it exactly in any position with a quick
action lock.

The Slit Lamp is shipped in a multi-layer foam
container and it is divided into major components :
Microscope, Instrument Body, Illumination
Column, Table Top and Chin Rest Assembly.
1. Take out the various parts. Remove the
wrapping. Make sure the wrapping does not
contain parts belonging to the instrument.
Save the packing.
2. Mount the headrest base from bottom of the
table top with the socket-head screws. and
hexagonal wrench (provided) as shown in Fig.
2. Connect the transformer ground wire under
one of the screws.
3. Plug the wire from the headrest assembly into
the connector on the back of the power supply
unit.
4. Attach head rest and chin rest assemblies with
the help of screw drivers as shown in Fig. 4.
5. Mount the table-top on appropriate instrument
stand arm or table base.
6. Position the Slit Lamp body gently on the table
so that the geared rollers mate with the teeth
on the guide rails. When the instrument is
pushed forward or pulled backwards, the
wheels should roll freely and evenly over the
guide-rails. (Refer Fig. 5)

Tightening the instrument base locking screw.
8. Mount the microscope head on the microscope
arm by sliding it into position, making sure it is
up against the stop. Then, tighten lock-knob
located on the right side of the microscope.
9. Plug the cable from the lamp arm into the
connector on the back of the power supply unit.

1. Turn the power using the ON/Off switch located on the
front of the power supply. Brightness can be adjusted
by rotating the illumination level knob.
NOTE : The maximum position is for intermittent use
only. Continuous use will shorten lamp life.
2. Insert the projection rod in the pivot post of the
instrument body to make rough PD and focus
adjustments. Position the light onto the flat surface
of the projection rod and adjust the pupillary
distance and focus of the eyepieces till a comfortable
viewing is obtained. Remove the projection rod.
3. To position a patient, adjust the chinrest height by
turning the control knob on the post of the headrest
assembly until the patient’s canthus is in line with
the canthus mark on the headrest post.
4. Microscope elevation is adjusted by rotating the
joystick and observing the Slit image through the
microscope until the slit is centered on the patient’s
cornea.
5. Move the Slit lamp with the joystick held firmly and
slightly angled toward the patient, until the slit
appears sharply on the cornea. The accuracy of this
rough adjustment should be checked by the naked
eye. The fine adjustment is performed while
observing the slit through the microscope.
6. Tilt the joystick, which is now held lightly at its upper
end, until the slit appears sharply at the depth of the
eye which is to be observed. The horizontal motion of
the base can be locked by tightening the base locking
screw. Lock the base whenever the lamp is not in
use.
7. The slit width can be adjusted by rotating the slit-
width control on either side of the instrument.
8. The angle between the illumination system and the 0 0microscope can be varied between 0 to 90 to either
the left or to the right. The angle is indicated on the

scale of the slit lamp arm.
9. Magnification is altered by rotating the dial on the
microscope head. The magnification of each click-
stop position is engraved on the dial.
10. Three filters are provided for cool and comfortable
view. This can be achieved by turning the filter dial.
1. Open the lamp house by opening the two screws (1)
& (2). See fig 8.
2. Open the lamp locking screw (2) to un-secure the
lamp holder. See fig 9.
3. Detach the power cord (1) from the lamp house.
4. Remove the lamp socket (2) from the lamp house.
Replace the blown lamp with live lamp and reverse
the procedure to secure the lamp house.
5. Open the fuse holder provided in the AC inlet on the
power supply.
6. The fuse holder has one live and one spare fuse.
Replace the dead fuse with the live fuse. Insert the
fuse holder back in the AC inlet plug.

7.1 Headrest / Chinrest Cleaning
For hygienic reasons, wipe the headrest and chin rest
with an alcohol wipe after each patient.
7.2 Changing Illumination Lamp
Ensure the Slit Lamp is switched Off and remember that
some parts may be hot. Do not touch the glass of the
new bulb.
Open the bulb access door. Swing the retaining spring
towards the arm pivot and pull the socket and bulb from
the housing. Note the position of the notch in the metal
collar of the bulb. Replace the bulb with a new one. Make
sure the notch is in the same position. Insert the bulb
and the socket into the lamp housing and move the
retaining spring back into position. Close the bulb
access door.
7.3 Projection Prism Cleaning
Grasp the narrow shank of the projection prism and pull
upwards. When cleaning the prism, blow with clean, dry
air, then gently wipe with a soft linen cloth.
7.4 Cleaning the Slide Plate
If the plate is dirty, it may cause a rough feeling when
maneuvering the base of the Slit Lamp. Clean the slide
plate with soft cloth lightly dampened with a mild soap
and water solution.
CONTINUOUS POWER SUPPLY
The Labomed Slit Lamp can be operated from 120 to 230
VAC. This is achieved by universal power supply. So
there is no need of adjusting the settings according to
the supply line voltage of the destination country.
NOTE : Two fuses are used in this unit. This is
recommended to replace the blown out fuses with the
fuses of same rating and type i.e. T 2.5L 250
More information on replacing the fuses can be found in
the maintenance section of this guide.
