 1.Anti-strong light The night vision system is designed with automatic anti-glare device. It will automatically protect when encountering strong light. Although the strong light protection function can maximize the protection of the product from damage when exposed to strong light, but repeated strong light irradiation will also accumulate damage. So please do not put products in strong light environment for a long time or many times. So as not to cause permanent damage to the product.。 2.Moisture-proof The night vision product design has waterproof function, its waterproof ability up to IP67 (optional), but long-term humid environment will also slowly erode the product, causing damage to the product. So please store the product in a dry environment. 3.Use and preservation This product is a high precision photoelectric product. Please operate strictly according to the instructions. Please remove the battery when it is not used for a long time. Keep the product in a dry, ventilated and cool environment, and pay attention to shading, dust-proof and impact prevention. 4.Do not disassemble and repair the product during use or when it is damaged by improper use. Please contact the distributor directly.  The DT-NH84X Night Vision can be connected with digital cameras, cameras, and video cameras. It can be used with a gun sight card or alone. The night vision instrument has a built-in infrared auxiliary light source and an automatic strong light protection system. This product has strong practicability and can be applied to military observation, frontier and coastal defense reconnaissance, public security surveillance, evidence collection, customs smuggling, etc. at the night without lighting. It is ideal equipment for public security departments, armed police forces, special police forces, and guard patrols.After the product has been dressed, in the actual use process, If the night vision device is not used for a while, night vision device can be flipped over the helmet. This does not affect the current line of sight,and is convenient to use at any time. When naked eyes need to observe, press the reversal button of the helmet mount, then turn the night vision assembly upward. , When the angle reaches 90 degrees or 180 degrees, loosen the reversal button of the helmet mount, the system will automatically lock the reversal state. When you need to put down the night vision module, you also need to press the flip button of the Helmet Pendant first. The night vision module will automatically turn back to the working position and lock the working position. When the night vision module is turned over to the helmet, the system night watch will be turned off automatically. When turning back to the working position, the night vision system will automatically turn on. And work normally. As shown in Fig.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)
