Gen2+ intensified tube night vision goggles

Directions for use:

1. Battery installation:

The CR123 battery (reference battery mark) is shown in Fig.

1.Tack the battery 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,Starting

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 adjustment

Choose a target with moderate brightness. The eyepiece is adjusted Without opening the lens cover. As in Figure 3, Turn the eyepiece hand wheel clockwise or counterclockwise. To match the eyepiece, when the most clear target image can be observed through an eyepiece,The eyepiece adjustment is complete. Different users need to readjust according to their vision.

4.  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 above method. When adjusting the objective lens, choose a dark environment target. As shown in Figure 4, 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.

5. 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. As shown in Fig. 2.

6. 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.

7. 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.
