1. Battery installation

The CR123 battery (reference battery mark) is shown in Fig. 1 Tack the attery into night vision battery cartridge. Lets battery cover and batteryCartridge’s  screw thread together ,Then clockwise rotation and tightened to complete the battery installation.


2. On/ off setting

As shown in Fig. 2, Turn the work switch along the clockwise direction.The knob indicates the location of "ON", when the system starts to work.


3. Eyepiece distance adjustment

As shown in Fig. 3, connect the bracket as the axis, and hold both
sides of the night vision instrument with both hands
Rotate clockwise or anticlockwise. Different users can use it
according to their own Adjust the distance between eyes and
comfort until it is suitable for the distance between eyes.


4. Eyepiece adjustment

Choose a target with moderate brightness. The eyepiece is adjusted
Without opening the lens cover. As in Figure4, Turn the eyepiece
hand wheel clockwise or counterclockwise. To match the eyepiece,
when the most clear target image can be observed through an eyepiece,


5. Objective lens adjustment

The objective adjustment is need to see the target at different distances.
Before adjusting the lens, must adjust the eyepiece according to the abovemethod. When adjusting the objective lens, choose a dark environment target. As shown in Figure 5,Open the lens cover and aim at the target.
Turn the focusing hand wheel clockwise or counterclockwise.
Until you see the clearest image of the target, complete the adjustment of the objective lens. When observing targets at different distances, the objective needs to be adjusted again according to the above method.

6. Operation Mode

The working switch of this product has four gears. There are four modes in total, except OFF.
There are three modes of work: ON, IR and AT. Corresponding to normal working mode, infrared auxiliary mode and automatic mode, etc.

7. Infrared mode

The environmental illumination is very low (all black environment). When the night vision instrument cannot observe clear images, The working switch can be turned clockwise to one shift. As shown in Fig. 2, The system enters the "IR" mode. At this time, the product is equipped with infrared auxiliary lighting to turn on. Ensure normal use in all black environments.
Note: in IR mode, similar equipment is easy to be exposed.

8. Auto Mode

The automatic mode is different from the "IR" mode, and the automatic mode starts the environment detection sensor. It can detect environmental illuminance in real time and work with reference to illumination control system. Under extremely low or extremely dark environment, The system will automatically turn on infrared auxiliary lighting, and when the environmental illumination can meet normal observation, The system automatically closes "IR", and when the ambient illumination reaches 40-100Lux, The whole system is automatically shut down to protect the photosensitive core components from damage by strong light.

Common Questions:

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).


1. Anti-strong light
The night vision system is designed with automatic anti-glare device. It will automatically protect when encountering strong light. Although the strong light protection function can maximize the protection of the product from damage when exposed to strong light, but repeated strong light irradiation will also accumulate damage. So please do not put products in strong light environment for a long time or many times. So as not to cause permanent damage to the product.。

2. Moisture-proof
The night vision product design has waterproof function, its waterproof ability up to IP67 (optional), but long-term humid environment will also slowly erode the product, causing damage to the product. So please store the product in a dry environment.

3. Use and preservation
This product is a high precision photoelectric product. Please operate strictly according to the instructions. Please remove the battery when it is not used for a long time. Keep the product in a dry, ventilated and cool environment, and pay attention to shading, dust-proof and impact prevention.

4. Do not disassemble and repair the product during use or when it is damaged by improper use. Please
