EMC/RFI
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 14.4°F (8°C).

STORAGE & CLEANING
The sensor lens is delicate. The lens should be kept clean at all times. Care should be taken when cleaning the lens using only a soft
cloth or cotton swab with water or ethyl alcohol. Allow the lens to fully dry before using the thermometer. Do not submerge any part of
the thermometer. The thermometer should be stored at room temperature between -4 and 149°F (–20 and 65°C).
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 32°F(0
o
C) or 122
o
F(50°C).
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.
‘Hi’ or ’Lo’ is displayed when the temperature being measured is outside of the measurement range.
BATTERIES
The thermometer incorporates visual low battery indication as follows:
‘Battery OK’: measurements
are possible
‘Battery Low’: battery needs to be
replaced, measurements are still possible
‘Battery Exhausted’: measurements are
not possible
When the ‘Low Battery’ icon indicates the battery is low, the battery should be replaced immediately with AAA, 1.5V batteries.
Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.
Dispose of used battery promptly and keep away from children.
