Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of
approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.
* Note: Under the electromagnetic field of 3V/m from 350 to 550MHZ, the maximum error is 8°C (14.4°F).
CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT.
2. USE EXTREME CAUTION WHEN OPERATING THE LASER.
3. NEVER POINT THE DEVICE TOWARDS ANYONE’S EYES.

+65°C (-4~149°F).
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
「 」
「 」
‘Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient temperature. ‘Er3’ is
displayed when the ambient temperature exceeds 0oC(32°F) or +50oC (122°F).
The thermometer should be allowed plenty of time (minimum 30 minutes) to stabilize to the working/room
temperature.
「 」
Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset it, turn the instrument
off, remove the battery and wait for a minimum of one minute, reinsert the battery and turn on. If the error
message remains please contact the Service Department for further assistance.
