1. Check battery power of main unit and sensor unit before using. Do not place sensor unit and main unit from each other over the limit distance to prevent the fail transmission. And keep away from the interference objects or signals.
2. The limit distance between main unit and sensor unit is typically 100M (330 feet) in open space.
3. The distance between main unit and sensor unit is shorter than 100M while there are barriers between the set up positions of units. The optimum distance depends on the material of barrier or the construction of building.

4. Do not put sensor unit into fridge or the metallic sealed equipment (enclosure) directly for measurement. Because the signal of sensor unit is blocked and can't transmit to main unit successfully.
5. For measuring fridge temperature only put the thermocouple wire tip in fridge.
6. A & B input socket (A → as CH1 on main unit display and B → as CH2) can take 2 K-type thermocouples for measurement. Apply the different temperature range of K-type thermocouple to work with the need. The applicable range is -200°C ~ +1370°C.
7. Set up I.D. of sensor unit
※ 8. Install batteries -– always install main unit first and complete
I.D. set from panel keys and then install batteries into sensor unit and complete I.D. set from switch in battery slot. The I.D. code of main and sensor unit should be the same.
9. To ensure the data to be captured by the main unit the initial transmission from sensor unit acts aggressively by every 6 seconds once set up. After the 9th data, the transmission of sensor unit and the receiving of main unit is parallel corresponding to each other.
Attention: do not attempt to loose those 2 screws.

(A). Battery installation Always install main unit first and then sensor unit. Follow instruction of A & B as below to enable transmitting and receiving in good work.
1. Battery (alkaline) life time for main and sensor unit is one year round which mainly depends on the application in different temperature and environment. Use 2 AA size alkaline batteries each for main and sensor unit.
2. Battery life time depends on the working condition. Such as repeat search for signal (because of interruption) or frequent alarm will cut down the battery life time. Need to replace the new batteries while the low battery symbol (sensor unit) or (main unit) display.
3. Do not attempt to loose the screws marked on drawing. 4. Main unit has no power switch and can be power off from
removing batteries exclusively. 5. Contact the maker or deliver the thermometer back to the
maker for checking if it can't work after the batteries installation process is completed.

B. Battery installation of sensor unit
Follow the steps from dwg#1 to dwg# 7 to complete the installation.
(1) Loose 2 screws on battery door with Philips screw driver.
(2) Do not attempt to loose 4 crews marked on dwg#2.
(3) Choose I.D. by changing the switch in the battery slot before installing batteries. I.D. code from 1 to 8 (refer to page 6 (C)-7.). The I.D. should be the same as the main unit for transmitting and receiving recognition.
(4) Fasten screws on battery door after installing batteries. (1.5V AA size battery * 2) Be sure to put with the correct polarity as marked in the slot.
(5) After battery installation, the light on sensor unit is flashing to identify I.D. Then the light is flashing every 6 seconds and transmitting the data of each flashing. After the 9th data, the transmission of sensor unit and the receiving of main unit is corresponding to each other and go into regular cycle by transmission/receiving every 3 minutes. Each flash of light means transmission is working and main unit refresh display of CH1 & CH2 every 3 minutes as well.
(6) In 1 minute after battery installation, check main unit if display any reading of temperature from sensor unit. If not, please make sure if I.D. of main and sensor unit is the same. And check if batteries are well installation and light is flashing during transmission of data. If all those are positive but still can’t find any reading on main display, please contact the maker for problem remove or deliver the thermometer back to the maker for checking.
2. Once batteries are installed the full segment will display on LCD for 2 seconds.

temperature corresponds with real time record. Recording is every 30 minutes with 24 sets maximum. Once capacity is full will start over the recording cycle from the beginning and the old record will be replaced. (Note: The record is made on every 30 minutes clock time. If initial clock time set at 13:52, the first data is at 14:00 and if the initial time is 12:17 the first data is 12:30 and the 2nd is at 13:00 and so on.).
(2) Push MODE key twice to switch from dwg#1 to dwg#2. The auto data logging function actuates once clock time is set.
(3) Push SEARCH key to read the previous data in memory. (dwg#2~4).

f. Activate alarm function ( display):
● Push MODE key to switch dwg#1 to dwg#2
● Alarm function is available simultaneously at CH1 and CH2. Once activate alarm function (as dwg#2), if temperature at CH1 or CH2 is over the temperature alarm point (higher or lower) the audible beeper will be on and lasting 2 minutes. Beeper will stop in 2 minutes automatically or push SEARCH key by manual stop. Push MODE key twice to return the simple measuring mode as dwg#1.
● Once temperature at CH1 or CH2 meets the alarm condition will activate audible beeper and “ ” and “HI” or “LO” symbols are flashing. Even stop beeping (automatically or manually) , the symbols are remained flashing to alert the user the temperature ever exceeds the alarm point. If the next coming data is still over the alarm point the beeper will generate again to repeat beep for 2 minutes and symbols are flashing.

At dwg#1, push MAX/MIN key to enter MAX/MIN recording mode. Push MAX/MIN key to shift reading maximum & minimum temperature at CH1 & CH2. Hold MAX/MIN key for 2 seconds to exit MAX/MIN mode and enable operating other functions.
At dwg#1, hold MODE & SEARCH keys simultaneously for 3 seconds (6 seconds for CH2) to enter alarm setting at CH1. After setting the temperature point, in 15 seconds will go back to simple measuring mode (dwg#1) automatically. (or push MODE to complete setting).
At dwg#1, hold MODE key for 3 seconds to enter clock set mode. In 15 seconds will go back to simple measuring mode (dwg#1) automatically. (or push MODE to complete setting).

WARNING
TO AVOID ELECTRICAL SHOCK, DO NOT APPLY INPUT VOLTAGE OVER DC60V OR AC24V
WARNING
TO AVOID DAMAGE OR BURNS, DO NOT PUT THE THERMOMETER IN MICROWAVE OVENS OR STOVE F O R M E A S U R E M E N T O R A P P L Y F O R T H E MEASUREMENT OF ELECTRICAL USE.
Attention
The repeated sharp flexing can break the thermocouple leads. To prolong lead lifetime, avoid sharp bend in the leads, especially for the cable relief to connector.
ACCESSORIES
Maintance
Do not attempt to open case of sensor unit or main unit (except battery door) to avoid the inaccuracy of measurement. Keep dry hands while replacing batteries. Do not use organic solvent to clean the thermometer but with soft cloth if necessary.
