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 re-
charge the rechargeable battery every 3 months.
Store the half-charged battery pack in a dry, cool and well venti-
lated 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 tempera-
ture 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 elec-
trolyte 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. Ex-
treme temperatures reduce the lifetime 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.
