2.1. SYSTeM DeSCRIPTION the atN NVM-14 is a hand-held, head-mounted, helmet-mount- ed, or weapon-mounted night vision system that enables walking, short-range surveillance, map reading, vehicle maintenance, and administering first aid in both moonlight and starlight. each unit al- lows for vertical adjustment (by using head straps), fore-and-aft adjustment, objective lens focus , and eyepiece focus.
- GreeN – serves as an excessive Brightness Indicator. If the bright light remains unchanged for over 10 seconds after the in- dicator turns on, the monocular will automatically shut off. If you move the unit away from the bright/excessive light the unit will turn back on again.

TYpE USAgE Cr123a 60 Hours (Gen. 2+) 50 Hours (Gen.3 and 4) Standard aa 30 Hours(Gen. 2+) 25 Hours (Gen.3 and 4) the atN NVM-14 operates with one Cr123a battery or one aa bat- tery using the battery adapter.
With the battery adapter (A) screwed in as shown on Figure 4.1 you may use one Cr123a 3V lithium battery. FIGURe 4.1. CR123A BATTeRY INSTALLATION to install a aa battery, take the battery adapter (a) out of the bat- tery cap (B), turn it over, and screw its smaller threading into the same battery cap.
MEChANICAl FUNCTIONS the mechanical functions of the atN NVM-14 allow for differences in the physical features of individual operators and provide for the system operation. these functions include the On/Off/On IR con- trol, eye relief (Section III Mounting procedures), diopter adjust- ment, objective lens focus, and IR illuminator focusing.
C. INFRAReD (IR) ILLUMINATOR OPeRATIONS CAUTION The IR illuminator is a light that is invisible to the unaided eye for use during conditions of extreme darkness. Please note that, the light from the illuminator can be detected by others that are using night vision devices. NOTE The purpose of the illuminator is to view at close distance up to 3 meters when additional illumination is needed.
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. SHADING FIGURe 5.1.
(Figure 5.2). to check for edge glow, block out all light by cupping a hand over the lens. If the image tube is displaying edge glow the bright area will still show up. Contact atN or point of purchase for warranty/repair procedures.
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.
3. BLACK SPOTS. these are cosmetic blemishes in the image intensifier or dirt or de- bris between the lenses. Black spots are acceptable as long as they do not interfere with viewing the image. No action is required if this condition is present unless the spots interfere with the usability of the device.
5. ChICKeN WIRe. an irregular pattern of dark thin lines in the field of view ei- ther throughout the image area or in parts of the image area (Figure 5.5). Under the worst-case condition, these lines will form hexagonal or square-wave shaped lines. this is typically viewed in high light conditions.
