Common problem:
1.No power
A. please checks whether the battery is loaded.
B. checks whether there is electricity in the battery.
C. confirms that the ambient light is not too strong.
2. Target Image is not clear.
A. check the eyepiece, whether the objective lens is dirty.
B. Check the lens cover open or not ?if at night time
C. confirm whether the eyepiece is properly adjusted (refer to eyepiece adjustment operation).
D. Confirm the focusing of the objective lens ,whether finished adjusted.r (referring objective lens focusing operation).
E. confirms whether infrared light is enabled when the environments all back.
3.Automatic detection not working
A. automatic mode, when glare automatic protection does not work. Please check if the environmental testing department is blocked.
B. flip, the night vision system does not automatically turn off or install on the helmet. When the system is in normal observation position, the system cannot start normally. Please check the position of the helmet mount is fixed with the product. (reference headwear installation)
