
During operation, if the camera is to be moved from hot/cold place to
cold/hot place, e.g. from inside/outside to outside/inside of a room,
switch off the camera and leave it in the new workplace for ca.
60 minutes. Only after that time, turn it on and start normal operation
with an accurate temperature measurement. Sudden and rapid
changes in ambient temperature may cause fault temperature meas-
urement and even damage camera's IR detector.

Calibration of the detector – during operation, the camera performs
auto-calibration from time to time, which takes approx. 2 seconds and
which is signalled by "Calibration" message at the bottom of the
screen.

Due to continuous development of the instrument's software,
the actual appearance of the display may slightly differ from
the display presented in this manual.

To maintain required parameters of rechargeable batteries,
unused rechargeable batteries should be charged every 3
months.

does not ensure proper operation of the camera and may
