1 Safety
Before you proceed to operate the camera, acquaint yourself thoroughly with the present manual and
observe the safety regulations and specifications defined by the producer.
Any application that differs from those specified in this manual may result in damage to the de-
vice and constitute a source of danger for the user.
The camera must not be used in rooms where special conditions are present e.g. fire and explo-
sion risk.
It is forbidden to use damaged or malfunctioning camera.
When the camera is not used for a long time, remove the batteries.
Do not use the camera with half-closed or opened battery cover and do not use any other adapter
than the one supplied with the camera.
Repairs may be performed only by an authorised service point.
KT-165 / KT-250 / KT-320 thermal camera is designed to measure and record the images in the infra-
red. It is designed to provide the user with maximum performance and safety during the work. How-
ever, the following guidelines and recommendations must be observed at all times (in addition to all
binding precautions applicable at individual work stands and work areas):
Keep the camera steady when performing the measurements.
Do not use the camera in temperatures exceeding its working and storage temperature ranges.
Do not direct the camera toward very high intensity radiation sources such as the sun, la-
sers or welding arcs etc.
Do not expose the camera to dust and moisture. When operating the device near water, ensure
that it is adequately guarded against splashes.
When the camera is not in use or is to be transported, ensure that the unit and its accessories
are stored in the protective carry case.
Do not re-switch on the camera until 15 seconds later after switching it off.
Do not throw, knock or shake intensely the camera and its components in order to avoid the
damage.
Do not attempt to open the camera body, as this action will void the warranty.
Use only the SD memory card supplied with the camera.
During operation, if the camera is to be moved from hot/cold place to cold/hot place, e.g. from in-
side/outside to outside/inside of a room, switch off the camera and leave it in the new workplace
for 20 minutes. Only after that time, turn it on and start normal operation with an accurate tem-
perature measurement. Sudden and rapid changes in ambient temperature may cause fault tem-
perature measurement 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 bot-
tom 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. When the camera is not used for a
long time, remove the batteries and store them separately.

CAUTION!
KT-165 / KT-250 / KT-320 thermal camera has no parts that could be repaired by
the user. Never attempt to disassemble or modify the camera. Opening the device
will void the warranty.
Use only standard and additional accessories, listed in section 8. Using other ac-
cessories does not ensure proper operation of the camera and may cause its dam-
age.
