c.Ranging module

As shown in Fig. 2-4, after the main control switch is turned ON, the low-light function and ranging function of the night vision device will automatically start to work. Turn the switch clockwise to the ON/IR/AUTO three gears, each of which can operate the ranging function. The auxiliary control switch controls access to the menu of the ranging function. Can achieve the function: single ranging, high frequency continuous ranging (2-10 seconds/time), low frequency continuous ranging (10-20 seconds/time), through the auxiliary switch can also adjust the ranging menu brightness.

d.Video input version

After the main control switch is turned ON, the night vision device’s low-light function starts to work, and the switch is rotated clockwise to the three gears ON/IR/AUTO. The auxiliary control switch can control the video input functions  {video brightness /mode / contrast /horizontal offset}.

As shown in Fig. 2-5, the video input interface is connected with a dedicated data cable, and the other end is connected with a signal cable and an external power supply respectively. Because the video input function needs to be powered separately, an external battery box can be worn to power the video input function for a long time. The low-light part uses electricity independently（CR123A(1)）.

3.Eyepiece distance adjustment

Select a target with moderate ambient brightness and adjust the eyepiece without opening the objective lens cover. As shown in Fig.5, turn the eyepiece hand wheel clockwise or counterclockwise to match the visual acuity of the human eye. When the clearest target image can be observed through the eyepiece, the eyepiece adjustment is completed. When used by different users, they need to readjust according to their own vision.

4.Objective lens adjustment

Objective lens adjustment is to see objects at different distances. Before adjusting the objective lens, adjust the eyepiece according to the previous method. When adjusting the objective lens, select a dark environment target. As shown in Fig.3, open the objective lens cover, align with the target, turn the objective lens focusing hand wheel clockwise or counterclockwise, until you see the clearest environmental image, and complete the objective adjustment. When observing objects at different distances, the objective lens needs to be adjusted again according to the above method.

5.Infrared mode

When the ambient illumination is very low (all black environment), so that the night vision cannot observe clear images, you can turn the working switch clockwise for another gear. As shown in Fig. 1-2, the system enters the “IR” mode. At this time, the built-in infrared auxiliary lighting of the night vision is turned on to ensure normal use in the all-black environment.

Note: In infrared mode, if similar equipment is encountered, it is easy to expose the target.

6.Auto Mode

The automatic mode differs from the “IR” mode in that the automatic mode activates the environmental detection sensor, which can detect the ambient illumination in real time and work with reference to the illumination control system. When the ambient illumination is low or all black, the system will automatically turn on the infrared auxiliary lighting. When the ambient illumination can meet the normal observation, the system will automatically turn off the “IR”. When the ambient illumination reaches 40-100Lux, the whole system will automatically turn off to protect the core components from being damaged by strong light.

7.Head-mounted installation

First, switch the helmet hanger device to the unlocked state, as shown in Fig.7-1. Push the lock latch of the helmet hanger device to the right to make the lock bolt spring back into the helmet hanger device, as shown in Fig7-2.

As shown in Fig.7-3, align the buckle of the helmet mounting fastener with the universal slot of the helmet, release the buckle to eject the lock core, and press gently to complete the installation. After the helmet mounting device is installed on the helmet, align the universal clamp of the night vision device with the device slot of the helmet mounting device by the eyepiece, and press the clamp inward (in the arrow direction), as shown in Fig.7-4, until you hear a click and release the device. The night vision is assembled .

8.Helmet adjustment

In order to ensure the adaptability of users when using this system, the helmet pendant system is designed with perfect fine-tuning structure to meet the needs of different users. Up and down adjustment: When it is necessary to adjust the up and down distance between the night vision eyepiece and the human eye, first turn the lock knob in the direction marked Open to unlock it, and then adjust it up and down after unlocking it. After adjusting the product eyepiece to the height most suitable for observation, turn the lock knob in the direction marked lock to lock it, and complete the up and down adjustment, as shown in Fig.8 in brown. Front and rear adjustment: When you need to adjust the distance between the eyepiece and the human eye, hold down the front and rear adjustment latches on the left and right sides of the night vision component at the same time. Do not let go. Slide the night vision component forward and backward and adjust it to an appropriate position. Rollover fine-tuning: The rollover fine-tuning knob has two gears. When rotated clockwise or counterclockwise, it can fine-tune the distance between the eyepiece and the human eye. As shown in blue.

9.Head flip

After the product has been worn, if the night vision is not used temporarily during the actual use, it can be turned over and placed on the helmet, so that the current vision will not be affected and it is convenient to use at any time. When you need to observe with naked eyes, hold down the flip button of the helmet pendant, as shown in Fig.9-1, to turn the night vision component upward. When the rotation Angle reaches 170 degrees, release the flip button of the helmet pendant, and the system will automatically lock the flip state, as shown in Fig.9-2. When you need to put down the night vision component for observation, you also need to press the flip button of the helmet pendant first. The night vision component will automatically turn back to the working position and lock the working position, as shown in Fig.9-2. When the night vision module is turned over to the helmet, the system night vision device will automatically be turned off. When it is turned back to the working position, the night vision device system will automatically start and work normally.
