Trouble Shooting, Appearance of the Device

7. TROUBLE SHOOTING

The stabilizing mode does not work.

Check that the batteries are installed properly. Check the charge of the batteries. Replace if they are weak. Do not use old batteries with new ones.

The image does not appear in focus.

Bring the inspected object to the center of the image. Turning the eyepieces (8), adjust to achieve the clearest image on the screen. If the view still does not seem in focus, clean the lenses. They could be foggy or dusty.

Image is ‘waving’ when stabilizing mode has been engaged. This is a typical ‘warming-up’ effect that will last for no more than one minute after engaging the stabilizing mode.

Condensation accumulates on the parts

In order to avoid misting of the eyepiece lens in cold time use special protective covers.

Image has disappeared during nighttime observation (using optional night eyepieces).

When bright light gets into the objective lens of the night vision device it may result in disappearing of the image as the automatic shut-off feature comes into action to protect the device. Whenever this happens, turn the switch to the OFF position. In a minute or two the device will be ready for further operation.
