A bright spot is a small, non-uniform, bright area that may flicker
or appear constant (Figure 5-3).
Not all bright spots make the ATN NVM-14 rejectable. Cup your
hand over the lens to block out all light. If the bright spot remains,
return the ATN NVM-14. Bright spots usually go away when the
light is blocked out. Make sure any bright spot is not simply a
bright area in the scene you are viewing.
Bright spots are
acceptable if they do not interfere with the ability to view
the outside scene.
2. Emission points.

area and does not go away when all light is blocked from the
objective lens of the monocular (Figure 5-3). The position of
an emission point within the image area does not move. Not all
emission points make the ATN NVM-14 rejectable. Make sure
any emission point is not simply a point light source in the scene
