9 ways to use night vision goggles
1. Remove the night vision goggles from the jacket.
2. Open the battery cover and insert the battery into the battery groove with a coin.
3. The batteries are installed and the night vision goggles are ready to work.
4. Turn the switch to the ON position. Go to IR position if illumination is low. A night vision device that is normally turned on should see bright spots on the fluorescent screen and infrared irradiator.
5. Remove the objective lens cap.
6. Aim the night vision device at the observed target, turn the eyepiece to find a clear image.
7. Adjust the eye reference along the barrel of the night vision goggle.
8. After the night vision device is working, turn the switch to OFF and cover the objective lens cover. It can still work for 10-15 minutes after turning off the night vision device (for the battery to fully discharge). This feature can be used to extend the working time of the battery.
9. It is recommended to take out the battery after the night vision device is working to prevent the battery dielectric from polluting the battery box.
When the switch is turned on and the fluorescent screen does not glow or the glow is very dim, the battery should be replaced. If the battery pollutes the surface of the battery box, wipe it with a soft cotton cloth or cotton ball. If the battery box is damp, it should be dried. For example, when cleaning the optical surface of the objective lens, eyepiece, and infrared irradiator, first blow off the small gravel and dust, and then rub the surface with a soft cloth.
