B. Product description
D-W1093 is the best gen1+ night vision hunting sight at its class that comes with affordable price and high performance.It’s equipped with a built-in powerful and safe IR illuminator providing clear and sharp image in total darkness. The accuracy is unparalleled thanks to the “Red on Green”reticle system. It can be adjusted vertically and horizontally to help find back zero reticle position for different distances or move the reticle exactly to the required areas. It’s widely used for police shooting training, hunting in the wild and shooting rehearsal of security personnel.
It’s better to use device under +5°C to +40°C. After the unit usage in temperatures below zero, wait at least 3 hours at room temperature, to avoid condensation accumulating on the internal lens surfaces and the consequent fogging caused by extreme temperature differences.
Keep the device in soft carrying bag, ventilated and dry place with temperature which does not exceed +15°C. Keep away from heating device and avoid direct sunlight and high humidity which does not exceed 70%.
NVD 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.
Use good quality lithium battery or alkaline cell, as bad quality batteries will effect the performance of the NVD and easily damage the device.
Try to avoid the rain and mist, and avoid dropping, shaking and collision.
Use clean soft cloth and dampened in alcohol,if necessary.
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.
If the device does not turn on
Reinstall the battery with the correct polarity.
Clean the battery compartment, focusing on the contact points.
The observed image flickers or flashes
This means there is too much light(e.g. observation during twilight conditions).Turn off the unit or place the objective lens cover. The unit will function normally in light conditions not in excess of 0.1Lx(full moon).
The image is missing or not focused
Re-focus the unit by adjusting objective lens. Adjust diopter setting by rotating eyepiece, if necessary.
Check the cleanliness of the objective surface and eyepiece and clean if necessary.
In extreme low light conditions, activate the built-in IR illuminator.
Image disappeared or its quality worsened
Automatic shut off might occurred to protect the unit from excessive light. Attach the objective lens cover and ensure that unit started to function normally. Turn the unit off and wait until the conditions darken to continue observation.
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.
You see black dots on the screen
These dots are minor cosmetic blemishes resulting from the image intensifier production processes and are not a sign of a defective or low quality unit. These dots do not interfere with the reliability and performance of the monocular.
G.Testing for all our devices
vibration test, high temperature test, lens resolution test, rain test, waterproof test, glass transmittance test, shock resistance test etc.
Our warranty is 2 years from the date of purchase.
