7. TROUBLESHOOTING
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 night-time 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.
