Maintenance
1.
Changing the batteries
If the battery symbol appears in the display, the batteries must be changed. The
four button cells are accessible after opening the battery compartment at the rear
of the unit. The used batteries must be removed from the battery holders and
replaced by new button cells of the same type. Only LR44 type batteries may be
used. Care must be taken to ensure that the polarity is correct when inserting.
The plus terminal of all four batteries should point upwards. The batteries must
be checked to see that they are properly seated before closing the battery
compartment.
2.
Cleaning
Clean the unit using only a dry cloth. If the unit is very dirty, the cloth may be
slightly dampened. Do not use cleaners containing solvents. Make sure that no
moisture enters the interior of the unit. When cleaning the lens, loose particles
must be removed using compressed air. Any remaining dirt can then be
removed with a soft brush or with a cotton swab moistened with water.
CAUTION
Do not use cleaners containing solvents.
Fastening the Infrared Thermometer
A soft-sided pouch with a belt loop and a quick release neck strap are included with
the infrared thermometer. To attach the infrared thermometer to the neck strap
simply insert the clip of the neck strap into the buckle end of the thermometer until it
clicks. To release, press both sides of the clip on the neck strap and pull the buckle
end until it is free.
