longed period of time or after approx. 10 mea-
surements, the warning notice will appear by the
segment indicator for CL

on the top left of the
LCD display

and the green backlight

of the
thermometer will blink twice and emit a signal tone

infrared sensor should be cleaned.
Calibration
The thermometer was calibrated in the factory fol-
lowing manufacture. If the thermometer is used in
accordance with the provisions and notices in the
user manual for private and non-commercial use,
there is no need to calibrate it at regular intervals.
If, however, you doubt the accuracy of the mea-
surements, you should immediately contact your
vendor.
Never attempt to disassemble the thermometer or
make changes as they could result in risks and in
such a case, also void any warranty claim!
