Bright Spots And Emission Points - ATN NVM14 Operator's Manual

1. bRIghT SpOTS.
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.
a steady or fluctuating pinpoint of bright light in the image area that
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 you are viewing. Emission
points are acceptable if they do not interfere with the usability
of the device.
