D. Features and Precations:
Unique Features:
1. IP67 weatherproof (as default for this model): When the device is soaked in water, within the defined pressure and time, the device does not enter the amount of hazardous water.
2. Automatic shut off when flipped up: The device will turn off automatically when pushing a button on the side of mount and lifting the unit up until reaches in the top position. Push the same button to lower monocular to the viewing position, then the device will turn on for continuation of operation.
3. No power consumption when in standby: It means no power consumption in case you forget to remove the battery for some days.
4. Embedded spring in battery's cap: It makes screwing the cap easier and better protects the spring and contact with the battery.
5. Fully adjustable head mount: The head mount can be adjusted according to head size.
6. Mil-spec multi-coated optic: Multi antireflection film can restrain the reflex of lens, which can reduce the loss of light so more light can go though the lens to get a sharp image.
7. Automatic brightness control: When the ambient light changes, the brightness of the image detected will keep the same to insure a stable viewing effect and also to protect users' eyesight.
8. Bright source protection: The device will shut off automatically in 10 seconds to avoid the damage of the image intensifier tube when the ambient light exceeds 40 Lux.
9. Low battery indication: A greenish light in the edge of eyepiece will start flickering when the battery is running low.
Precautions:
1. Do not disassemble the unit.
2. It's better to use device under -40°C to +60°C. After the unit usage in temperatures below zero, wait at least 10 mins at room temperature, to avoid condensation accumulating on the internal lens surfaces and the consequent fogging caused by extreme temperature differences.
3. Keep the device in soft carrying bag, ventilated and dry place with temperature which does not exceed +35°C. Keep away from heating device and avoid direct sunlight and high humidity which does not exceed 70%.
4. NVB should be used in nighttime and can't be aim at strong light. If you have to test it during daytime, the front lens cap should never be removed. You can observe the target through the hole in the protection cap.
5.Use good quality lithium battery or alkaline cell, as bad quality batteries will effect the performance of the NVC and easily damage the device.
6. Try to avoid the rain and mist, and avoid dropping, shaking and collision.
7. Use clean soft cloth and dampened in alcohol,if necessary.
8. A useful tip is to remove the battery when the night vision will be not in use for over 3 days to prevent battery leakage and damaging the device.
NOTE: It is normal that the device can not be turned on when the ambient light exceeds 40 Lux. This device has protection system, which cuts off the image intensifier when ambient light level exceeds the limit of 40 Lux during a 10 seconds period.
Failure to follow the above precautions may cause the unit damage and will void the manufacturer's warranty.
E. Troubleshooting:
If the device does not turn on
1.Reinstall the battery with the correct polarity.

2.Bright light sources(e.g. street lights)may cause visibility to decrease or disappear. Turn the monocular away from the light source, visibility will restore itself in several minutes.
