10. TROUBLE SHOOTING

]

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.
