When the camera is not in use or is to be transported, ensure that the unit and its accessories are storedin 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 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 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.

Power supply, battery charging

The camera is powered by an internal rechargeable battery. It may be also powered using the AC adapter.

In order to charge a KT camera, just plug in the AC adapter to the camera USB socket when it is switched off. Charging does not take place during operation of the camera.

If the camera is to be inactive for a long time, it is recommended to recharge the rechargeable battery every 3 months.

Store the half-charged battery pack in a dry, cool and well ventilated place and protect them from direct sunlight. The battery pack may be damaged if stored when fully discharged. The ambient temperature for prolonged storage should be maintained within the range of 5°C…25°C.
Charge the batteries in a cool, well-ventilated place at a temperature of 10°C … 28°C.
Modern fast chargers detect both too low and too high temperature of rechargeable batteries and react to the situation adequately. When the temperature is too low, charging should be prevented as it may irreparably damage the batteries. The increase in temperature of the battery pack may cause electrolyte leakage and even its ignition or explosion.
Do not exceed the charging current, as it may result in ignition or “swelling” of the battery pack.
“Swollen” battery pack must not be used.Do not charge or use the batteries in extreme temperatures. Extreme temperatures reduce the life-time of rechargeable batteries. Always observe the rated operating temperature. Do not dispose the battery pack into fire.
Li-Ion cells are sensitive to mechanical damage. This kind of damage may cause their permanent damage and thus ignition or explosion.
Any interference in the structure of Li-ion battery pack may cause its damage. This may result in the ignition or explosion.
A short-circuit of the battery poles “+” and “-” may permanently damage the battery pack or even cause its fire or explosion.
Do not immerse Li-Ion battery in liquids and do not store in humid conditions.
If the electrolyte contained in the Lithium-Ion battery pack, contacts eyes or skin, immediately rinse the affected place with plenty of water and consult a doctor. Protect the battery against unauthorised persons and children.
When you notice any changes in the Lithium-Ion battery pack (e.g. changes in colour, swelling, excessive temperature), stop using the battery pack. Li-Ion batteries that are mechanically damaged, overcharged or excessively discharged are not suitable for use.
Any misuse of the battery may cause its permanent damage. This may result in the ignition. The seller and the manufacturer shall not be liable for any damages resulting from improper handling LiIon battery pack.

Cleaning and maintenance

| NOTE!

Use the below specified methods of maintenance only.
The thermal imager does not comprise any parts serviceable by the user. Do not attempt to dismantle or modify the camera on your own. Opening the instrument voids the warranty.
