Objective adjustment

The purpose of objective lens adjustment to see clearly at different distances. Before adjusting the objective lens,Please adjust the eyepieces first according to the aforementioned method. When adjusting the objective lens, please select a darker environment. As shown in Figure ④, open the objective lens cover, aim at the target, and turn the objective lens focusing handwheel clockwise or counterclockwise until the clearest environment image is seen, and the objective lens adjustment is completed. When observing targets at different distances, the objective lens needs to be adjusted again according to the aforementioned method.

Infrared mode

When the ambient illuminance is very low (full black environment), and the night vision device cannot observe a clear image, you can turn the work switch clockwise to another gear. the system enters the "IR" mode. At this time, the built-in infrared auxiliary lighting of the product is turned on to ensure normal use in a completely dark environment. Note: In the infrared mode, if you encounter similar equipment, it is easy to expose the target.
