5-1 ZEROING OpERATIONAL dEFECTS
operational defects relate to the reliability of the image intensi-
fier and are an indication of instability. If identified, they are an
immediate cause for rejecting the atn nVM-14. they include
shading, edge glow, flashing, flickering, and intermittent opera-
tion.
A. SHAdING
If shading is persistent, you will not see a fully circular image
(Figure 5-1). Shading is very dark and you cannot see an image
through it. Shading always begins on the edge and migrates
inward eventually across the entire image area. Shading is a
high contrast area with a distinct line of demarcation. Contact
atn or point of purchase for warranty/repair procedures.

NOTE
Make sure the shading is not the result of improper exit pupil
position.
