G. Precautions


1. Do not disassemble the unit.

2. It’s better to use device under +5°C to +40°C. After the unit usage in temperatures below zero, wait at least 3 hours at room temperature,to avoid condensation accumulating on the internal lens surfaces and the consequent fogging caused by extreme temperature differences.

3. Keep the device in soft carrying bag, ventilated and dry place with temperature which does not exceed +15°C. Keep away from heating device and avoid direct sunlight and high humidity which does not exceed 70%.

4. NVD should be used in nighttime and can’t be aim at strong light. If you have to test it during daytime, the front lens cap should never be removed. You can observe the target through the hole in the protection cap.

5. Use good quality lithium battery or alkaline cell, as bad quality batteries will effect the performance of the NVD and easily damage the device.

6. Try to avoid the rain and mist, and avoid dropping, shaking and collision.

7.  Use clean soft cloth and dampened in alcohol,if necessary.

8.  A useful tip is to remove the battery when the night vision will be not in use for over 3 days to prevent battery leakage and damaging the device.


NOTE: It is normal that the device can not be turned on when the ambient light exceeds 40 Lux. This device has protection system, which cuts off the image intensifier when ambient light level exceeds the limit of 40 Lux during a 10 seconds period.

Failture to follow the above precautions may cause the unit damage and will void the manufacturer’s warranty.
