ATN ATN NVM14 manual Bright Spots and Emission Points Black Spots

2. Emission Points

A steady or fluctuating pinpoint of bright light in the image 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 emis- sion 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 ability to perform the mission.
