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).

4.  KEEP OUT OF REACH OF ALL CHILDREN. 
STORAGE & CLEANING 
The sensor lens is the most delicate part of the thermometer. 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 medical alcohol. Allowing 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 –20 to 
+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 0
o
C(32°F) or +50
o
(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. 
 
‘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.
