SAFETY SUMMARY CAUTIONS • The ATN NVM-14 is a precision optical instrument and must be handled carefully at all times to prevent damage. • Do not scratch the external lens surfaces or touch them with your fingers. • Wiping demisting shield with lens paper while wet or with wet lens paper can damage the coating. • To protect the image intensifier, keep the lens cap on the objective lens when the monocular is not in use or when checked out in daylight conditions.
NOTES • When utilizing the ATN NVM-14 for driving purposes, the goggles may not be used in the hand-held mode. The goggles must be worn in the head- or helmet-mounted position. • At operating temperatures below –20°C (-4°F), alkaline batteries are not recommended, as operating life will be severely reduced. Lithium-iron disulfide 1.5V AA batteries or equivalent should be used below –20°C (-4°F).
Equipment Limitations To avoid physical and equipment damage when using the ATN NVM-14, carefully read and understand the following safety precautions. • The equipment requires some night light (moonlight, starlight, etc.) to operate. The level of performance depends upon the level of light. • Night light is reduced by passing cloud cover, while operating under trees, in building shadows, etc. • The equipment is less effective viewing into shadows and other darkened areas.

SECTION III MOUNTING PROCEDURES
3.1 MOUNTING PROCEDURES A. Mounting the ATN NVM-14 to a HeadMount To mount the ATN NVM-14 to a headmount, perform the following: 1. Loosen the screw (A). Push the button (B) and insert the bracket of the NVM-14 into the rail (C) of the headset. 2. Place the headmount with NVM-14 onto a head. 3. Loosen the screw (A) and move the unit along the rail for eye relief adjustment. 4. The NVM-14 headmount has a flip-up mechanism.
B. Mounting the ATN NVM-14 to a helmet Helmet mount for attachment of ATN NVM-14 to a standard PASGT helmet. Helmet mount fits securely onto helmet via a rugged strapping device and grooved hooks. With helmet mount, NVM14 can be positioned directly in front of user’s eyes or flipped. 1. Install the mount onto helmet as shown on the picture. 2. Tighten and fixate the straps (A) 3. Attach goggles to the rail. 4. Loosen the screw (C).
CAUTION It is recommended that the eyecup be replaced with the eyeguard during weapon-mounted use. NOTE The ATN NVM-14 is not a weapon sight, however, it can be used in conjunction with a collimated dot sight or laser aiming device. C. Mounting the ATN NVM-14 to the weapon To mount the ATN NVM-14 perform the following: 1. Loosen the clamping knob on the weapon mount.
D. Mounting the ATN NVM-14 to a scope Day/Night System may be mounted with Flip-up Scope Adapter Mount for NVM-14 and variety of daytime scopes/telescopes. 1. Loosen the adapter fixing screws (A). 2. Put the insert into the adapter (ATN supplies inserts of different sizes for their coupling with 38 mm to 43 mm eyepieces). 3. Now attach the monocular to the bracket (B).
E. Mounting ATN NVM-14 on to ATN 3.5x26 scope There are special adapter for using the ATN NVM-14 with the ATN 3.5x26 riflescope. To mount the ATN NVM-14 perform the following: 1. Loosen the the mounting screw (A) of adapter. 2. Mount the adapter onto the back Picatinny rail of the ATN 3.5x26 riflescope. 3. Tighten the mounting screw of adapter. 4. Loosen the screw (B) of adapter. Push the button (C) and insert the bracket of the NVM-14 into the rail of the adapter. 5.
G. Mounting Camera/Camcorder to the ATN NVM-14 1. Screw Camera Adapter into the front lens of a photographic camera (thread M52x0.75) or a video camera (use adaptor ring threaded M37x0.75). 2. Remove the rubber eyecup off the monocular. 3. Connect the adapter with the eyepiece and tighten 3 fixing screws on the adapter. H. Mounting IR-450 to the ATN NVM-14 IR-450 may be mounted on the monocular through the Picatinny adapter. 1. Install the Picatinny Adapter on one of the monocular rails (See cl. 3.4.F). 2.
With this adapter you may see through the eyepiece using either right or left eye. To change the viewing eye, loosen the nut(C) and turn the adapter(D) in the point of connection to match with another eye. Tighten the nut(C) anew. To disconnect the adapter press the upper clip(E). 2. Align the headmount adapter and the head/helmet mount. Slide the monocular rearwards until the alignment boss aligns with the alignment groove on the head/helmet mount. Push until the monocular locks into the head/helmet mount.
SECTION IV OPERATING PROCEDURES
4.1 OPERATING INSTRUCTIONS a. Battery Installation CAUTION To protect the image intensifier, keep the lens cap on the objective lens when the monocular is not in use or when checked out in daylight conditions. NOTE At operating temperatures below –20°C (-4°F), alkaline batteries are not recommended, as operating life will be severely reduced. Lithium-iron disulfide 1.5V A A batteries or equivalent should be used below –20°C (-4°F).
Install CR123A batteries as follows: 1. Unscrew the battery cap (A) and insert the battery (B), observing the polarity as indicated. 2. Replace the battery cap (A) and screw cap hand tight.
Install standard AA batteries as follows: 1. Unscrew the battery cap (A). 2. Unscrew the CR123 battery adapter(B) from the cap. 3. Insert AA battery and, observing the polarity as indicated. 4. Replace the battery cap and screw cap hand tight.
b. Mechanical Functions The mechanical functions of the ATN NVM-14 allow for differences in the physical features of individual operators and provide for operating the system. These functions include the On /Off/On IR control, eye relief (see Section III Mounting Procedures – Headmount Adjustments), diopter adjustment, objective lens focus, and IR illuminator focusing. These mechanical controls are identified in Figure 4-3. Operation button (A) switches both the monocular and the IR Illuminator on/off.
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. However, the light from the illuminator can be detected by the enemy using night vision devices. NOTE The purpose of the illuminator is for viewing at close distance up to 3 meters when additional illumination is needed. IR Illuminator gets activated when the monocular is already on by holding button (A) pressed for 1,5-2 seconds.
SECTION V ZEROING OPERATIONAL DEFECTS
5-1 ZEROING OPERATIONAL DEFECTS Operational defects relate to the reliability of the image intensifier 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 operation. 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.
b. Edge Glow Edge glow is a bright area (sometimes sparkling) in the outer portion of the viewing area (see 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. Return the ATN NVM-14 to the maintainer.
c. Flashing, Flickering, or Intermittent Operation The image may appear to flicker or flash. If there is more than one flicker, check for loose battery adapter or weak battery. Return the ATN NVM-14 to the maintainer. d. Cosmetic Blemishes These are usually the result of manufacturing imperfections that do not affect image intensifier reliability and are not normally a cause for rejecting ATN NVM-14.
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 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 ability to perform the mission.
4. Fixed-Pattern Noise. This is usually a cosmetic blemish characterized by a faint hexagonal (honeycomb) pattern throughout the viewing area that most often occurs at high light levels or when viewing very bright lights (See Figure 5-4). This pattern can be seen in every image intensifier if the light level is high enough. This condition is acceptable as long as the pattern does not interfere with viewing the image and interfere with the ability to perform the mission.
5. Chicken Wire. An irregular pattern of dark thin lines in the field of view either throughout the image area or in parts of the image area (See Figure 5-5). Under the worst-case condition, these lines will form hexagonal or square-wave shaped lines. No action is required if this condition is present unless it interferes with the viewing the image and interferes with the operator’s ability to perform the mission.
