12. TROUBLESHOOTING
1. The projection does not turn on: batteries are completely dead or incorrectly
inserted; replace or reinsert them (par. #9).
2. The temperature is not projected between the two dots: the unit is not at the cor-
rect distance; move the thermometer forward or back until the projected temperature
falls pr
ecisely between the two dots (g. 5).
3. The projected temperature is not clearly visible: there is too much light in the room
or the batteries are low; cast a shadow over the subject or replace the batteries.
4.The sensor (g. 1) is damaged or water has seeped into the thermometer: contact
your Dealer right away for technical service.
5.The thermometer temperature reading is too low:
- make certain that the conditions outlined in the warnings (par. #2) have been met;
- check that the waveguide (g. 1) is not soiled or damaged; if it is, clean it as indi-
cated in par. #10 or contact your Dealer for technical service;
- check that the thermometer is perpendicular to the for
ehead as indicated in g. 3.
6. The temperature reading is too high: make certain that the conditions outlined in
the warnings have been met (par. #2).
7. The thermometer appears blocked or does not revert to stand-by after being idle
for 20 seconds, or the aiming LEDs remain on after the button is released: reset the
thermometer by removing and reinserting the batteries.

When the FACE button is used in rooms where the temperature is in the range 10,0-15,9°C (50.0-
60.7°F) or 40,1-45,0°C (104.1-113.0°F), accuracy and operating range are not guaranteed, and the
temperature value is displayed alternately with the message “Lo.5» or “Hi.4” respectively.
