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. Return the
ATN NVM-14 to the maintainer.

NOTE
Make sure the shading is not the result of improper eye-relief
adjustment.
