Product Description
DT-NH9X1 is a new product based on the latest optoelectronics technology. It uses high-performance second-generation/third-generation image intensifier. It features excellent performance, small size, light weight, clear imaging, video output, adjustable eye distance, and can change magnification by changing objective lenses (or connecting multiplier lenses). This product can be adjusted arbitrarily with different eye distance requirements. The built-in digital video acquisition system of the night vision instrument can easily realize the acquisition and transmission of digital video at night and without illumination, thus realizing the visual command coordination at night. Built-in red explosion lamp, infrared lighting and automatic strong light protection. This product has strong practicability and can be applied to mili-tary observation, frontier and coastal defense reconnaissance, public security surveillance, evidence collection, customs smuggling, etc. in the night without lighting. It is an ideal equipment for public security departments, armed forces, special po-lice forces, and guard patrols.

This product has four working switches, there are four modes in total, in addition to shutdown (OFF), there are also three working modes such as "ON", "IR", and "AT", which correspond to the normal working mode and the infrared mode , Auto mode, etc., as shown in Figure ..
First, turn the knob on the helmet mount device to theend of the clock counter clockwise. Then use the universal fixture of the night vision instrument to one end ofthe eyepiece to the equipment slot of the helmet hanging device. Press the device button on the helmet mount vigorously. At the same time, the night vision instrument is pushed along the equipment slot. Until the button of center is moved to the middle at the universal fixture. At this time, release the anti button, turn the equipment locking knob clockwise and lock the equipment. As shown in Fig. 5.After installing the night vision instrument, Fasten the pendant of helmet mount to the general equipment slot of the soft helmet. Then press the lock button of the Helmet Pendant. At the same time, the components of the night vision instrument and Helmet Pendant are rotated counterclockwise. When the helmet mount connector is completely attached to the universal equipment slot of the soft helmet, Loosen the lock button of the Helmet Pendant and lock the product components on the soft helmet. As shown in Fig. 6.
