In Figure 1-3, install the battery compartment using the No. 5 dry battery (the polarity of the battery label is used), align the battery cover with the thread of the battery container, and tighten the battery cover clockwise. The DTS-33N night vision device has realized the sharing of two batteries, so that the night vision device can adapt to different use scenarios.

2.On/ Off setting

As shown in Fig.2, rotate the switch one step in the clockwise direction, rotate the switch to the position of “ON”, the system is turned on, and then the system lights up the image tube and starts to work. (Clockwise rotation: ON/IR/AUTO) The infrared auxiliary light source is enabled in IR mode. The ATUTO file enters the automatic mode, etc., and switches successively. When it is closed, it needs to switch back to the OFF gear.

3.Eyepiece distance adjustment

After users wear this product, they can adjust the program spacing according to their own eye distance. Adjustment method: Adjust the left and right sides separately. First look at the right eyepiece with the right eye and adjust it until you see a complete round picture. Then close the right eye and look at the left eyepiece with the left eye and fine-tune the eye distance until you see a complete round picture. At this time, both eyes observe at the same time, can observe the complete circular picture, after the completion of debugging, the eyes can see the largest and clearest field of view.

Locking method: This night vision device is equipped with an eye distance locking hand wheel, as shown in Fig.3-1: it can be clockwise or counterclockwise

Turn the adjusting hand wheel to lock the eye distance, as shown in Fig.3-1, adjust the extension support rod counterclockwise, and shorten the support rod clockwise. Different lengths control different eye distances, and adjust the length well to lock the eye distance, as shown in Fig. 3-2, the eye distance has been locked, and the distance will not be reduced any more, and the same person can directly observe the next use. No need to adjust again. The eye spacing lock component is optional, and you can choose not to install this component for extreme lightweight.

When used by different users, you can adjust the distance and comfort of your eyes according to the previous method, after adjusting the eye distance, turn the first round of adjustment lock, you can achieve the eye distance lock.

4.Eyepiece adjustment

Select a target with moderate ambient brightness and adjust the eyepiece without opening the objective cover. As shown in Fig.4, turn the eyepiece hand wheel clockwise or counterclockwise to match the visual degree 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, it needs to be re-adjusted according to their own vision.

5.Objective adjustment

The purpose of adjusting the objective lens is to see the scenery at different distances clearly. Before adjusting the objective lens, please adjust the eyepiece according to the above method. When adjusting the objective lens, select a dark environment target. As shown in Fig.5-1, open the objective lens cover, align with the target, turn the focusing hand wheel of the objective lens clockwise or counterclockwise, until the clearest environment image is seen, and adjust the objective lens. When viewing objects at different distances, the objective lens needs to be calibrated again according to the above method.

5.1Objective focus lock

After adjusting the focus of the objective lens, if you need to observe the target at the same distance for a long time, you can use the objective lens focusing lock function to avoid focusing changes. As shown in Fig.5-2, the focusing hand wheel and locking ring of the objective lens are in place; As shown in Fig.5-3, focus the objective lens to the desired position and see a gap 1-2 mm wide; As shown in Fig.5-4, gently rotate the focusing lock ring to lock the focusing hand wheel. As shown in Fig.5-5, the focusing lock ring locks the focusing hand wheel, and the focusing range of the objective lens becomes smaller

5.2Eyepiece visual range adjustment

You can adjust the viewing range of the eyepiece when adjusting the viewing range, the general range is +5° to -5° You can adjust the range from -6° to +4°, to -4° to +6°, change the upper and lower limits of the viewing, so that the viewing is more convenient.

The process is as follows: If the eyepiece diopter is adjusted to +5° and still cannot see clearly, you can choose to adjust the viewing range to +6°. Method: As shown in Figure 5-6, turn the eyepiece optically adjusting hand wheel (1) clockwise until it does not move. As shown in Figure 5-7, rotate the eyepiece retaining ring (2) counterclockwise to reveal a thread of 1-2mm. As shown in Figure 5-8, turn the viewing range lock (3) counterclockwise and clamp it tightly with the eyepiece retaining ring (2). As shown in Figure 5-9, the adjustment is complete, and the upper limit of the diopter is +6° to -4°.

If the eyepiece diopter is adjusted to -5° but still cannot see clearly, you can choose to adjust the viewing range to -6°. Method: As shown in Figure 5-10, turn the eyepiece optically adjusting handwheel (1) counterclockwise until it does not move; As shown in Figure 5-11, rotate the eyepiece retaining ring (2) counterclockwise until it is loose. As shown in Figure 5-11, turn the range lock (3) clockwise to the end and tighten the eyepiece retaining ring (2) clockwise. The viewing range lock (3) and the eyepiece retaining ring (2) are clamped together. As shown in Figure 5-12, the adjustment is complete, and the diopter range is +4° to -6°.

1. Infrared mode

When the ambient illumination is very low (all black environment), resulting in the night vision device can not observe a clear image, you can turn the working switch clockwise again. When the system enters the “IR” mode, the built-in infrared auxiliary lighting of the night vision device 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. As shown in Figure 6, in infrared mode, you can see the internal infrared indicator light steady on through the eyepiece of the night vision device.

1. 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. In automatic mode, if the night vision device is in full black, the infrared light is automatically turned on. At this time, you can see the internal infrared indicator light on through the eyepiece. If the light becomes stronger, the infrared supplementary light is turned off, and the infrared indicator is turned off immediately.
