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 a hot/cold place to a 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 the camera’s IR detector.
Calibration of the detector – during operation, the camera performs auto-calibration from time to time, which takes approx. 2 seconds.
Due to the 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 the required parameters of rechargeable batteries, unused rechargeable batteries should be changed every 3 months.

CAUTION!

KT-128 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.

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 MicroUSB socket when it is switched off.
Charging does not take place during the 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 temperatures 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 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 lifetime of rechargeable batteries. Always observe the rated operating temperature. Do not dispose of the battery pack into the fire.
Li-Ion cells are sensitive to mechanical damage. This kind of damage may cause permanent damage and thus – ignition or explosion.
Any interference in the structure of the Li-ion battery pack may cause damage. This may result in 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 the eyes or skin, immediately rinse the affected place with plenty of water and consult a doctor. Protect the battery against unauthorized persons and children.
When you notice any changes in the Lithium-Ion battery pack (e.g. changes in color, 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 permanent damage. This may result in 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.
Camera enclosure – all surfaces, except for optical elements of the camera, can be cleaned with a soft and moist cloth with generally available mild detergents. Do not use any solvents or cleaning agents that could scratch the enclosure (powder, paste, etc.). During cleaning, the camera must be turned off.
Due to the applied anti-reflective coating, optical lenses are the most sensitive and at the same time the most expensive part of the camera (the lens is of key importance to the radiometric capabilities of the infrared system). Optical surfaces should be cleaned only when they are visibly fouled. Do not touch exposed surfaces of optical lens with fingers, because fouling left with fingerprints can be harmful to coatings and glass of the lens.
Chemical agents must not be used for cleaning the optics and accessories of the camera. Use a clean, dry and soft cloth.

Storing

When storing the instrument, observe the following guidelines:

make sure the camera and its accessories are dry,
allowed are storage temperatures specified in technical specifications,
in order to avoid complete discharging of rechargeable batteries during prolonged storage, charge them once in a while (recommended time: 3 months).

Dismantling and disposal

Used-up electrical or electronic equipment must be collected selectively, i.e. must not be mixed with the waste of other types.
Used-up electronic equipment must be delivered to an appropriate collection center in accordance with regulations related to used-up electrical or electronic equipment.
Before delivering the equipment to the collection center do not attempt to dismantle any of its parts.
Follow local regulations related to disposing of packaging, used-up batteries, and rechargeable batteries.
