10. TROUBLESHOOTING
]
The scope 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
objective lens ring (10), and/or the eyepiece (3) adjust to achieve the
clearest image on the screen. Repeat the steps of focusing if necessary.
If the view still does not seem in focus, clean the lenses. They could be
foggy or dusty.
Image has disappeared.
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.
If the image has been lost at the moment of a shot, check contacts in the
battery compartment.
Condensation accumulates on the parts
In order to avoid misting of the eyepiece lens in cold time use special
protective covers.
Indistinct movement of aiming reticule.
When adjusting the scope it is desirable to rotate the screw of horizontal
replacement for 2-5 clicks in one direction, and then put the vertical
adjustment screw in the initial position.
Black dots on the screen
These are the cosmetic blemishes in the image intensifier, that do not
affect the performance or reliability of a night vision device and some
number of varying size are inherent in the manufacturing process. Most of
them are seen at daytime only and become almost invisible during the
nighttime operation.
Bright spots on the screen
The image may contain some bright spots caused by gradual relief of
static electricity from the cathode. This feature may appear immediately
after the assembling of the device or attaching/detaching of the objective
lens, and it always disappears within 5-14 days of usage or storage.
