DT - NH8XD is based on the latest optoelectronics technology research and development of new products,，The instrument adopts the high-performance image intensifier tubes, with excellent performance, small volume and weight ,light, clear imaging, simple operation, high cost performance, and by replacing the objective lens (or connecting multiplier lens). It can change magnification and so on. The product is connected with a special binocular connector to become a binocular binocular night vision device, and can also be disassembled as two monocular night vision devices. The night vision instrument is equipped with an infrared auxiliary light source and an automatic anti glare protection system. The product has strong practicability and can be applied to military observation, coastal defense reconnaissance, public security surveillance, forensics, customs anti-smuggling, etc. in no illumination environment at night. It is an ideal equipment for public security department, armed police force, special police force and guard patrol.

 1.No power A. please checks whether the battery is loaded. B. checks whether there is electricity in the battery. C. confirms that the ambient light is not too strong. 2. Target Image is not clear. A. check the eyepiece, whether the objective lens is dirty. B. Check the lens cover open or not ?if at night time C. confirm whether the eyepiece is properly adjusted (refer to eyepiece adjustment operation). D. Confirm the focusing of the objective lens ,whether finished adjusted.r (referring objective lens focusing operation). E. confirms whether infrared light is enabled when the environments all back. 3.Automatic detection not working A. automatic mode, when glare automatic protection does not work. Please check if the environmental testing department is blocked. B. flip, the night vision system does not automatically turn off or install on the helmet. When the system is in normal observation position, the system cannot start normally. Please check the position of the helmet mount is fixed with the product. (reference headwear installation)
