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.

• 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 when
using night vision devices.

• If you use the rubber eyecaps for a long period of time, you may
suffer skin inflammation. If you develop any symptoms, consult
a doctor immediately.

a

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).

• The purpose of the illuminator is for viewing at close distance
up to 3 meters when additional illumination is needed.

b

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.

• The equipment is less effective through rain, fog, sleet, snow or
smoke.

• The equipment will not “see” through dense smoke.

• Adjust vehicular speed to prevent overdriving the range of view
when conditions of possible reduction or loss of vision exist.

EQUIPMENT DESCRIPTION

2.1 SYSTEM DESCRIPTION

The ATN NVM-14 is a hand-held, head-mounted, helmet­mounted, or weapon-mounted night vision system that enables
walking, driving, weapon firing, short-range surveillance, map
reading, vehicle maintenance, and administering first aid in both
moonlight and starlight. Each unit allows for vertical adjustment
(by using head straps), fore-and-aft adjustment, objective lens
focus, and eyepiece focus. The device is also equipped with an
infrared light-emitting source.

NVM-14 Night Vision monocular utilizes the principle of intensi­fication of the residual light which is reflected from the surround­ing objects. The optical system of the monocular consists of: an
objective lens, an image intensifier tube and an eyepiece.

Even under unsteady brightness conditions, Automatic Bright­ness Adjustment System always keeps the IIT brightness level
constant.

The Automatic Protective System controls the existing illumina­tion level through the photo receiver. If the illumination level sur­passes 100-300 lx for the following 10 seconds, the monocular
will shut off automatically

Built-in IR Illuminator makes it possible to observe the objects
when the monocular works in the conditions of low light or total
darkness.

The eyepiece incorporates several LED indicators:

- RED – serves as an IR Illuminator Indicator and an Battery Low
Indicator at a time. IR is on when the indicator light becomes
stable. If the indicator light starts flickering, it means there might
be about 20% of battery charge left.

- GREEN – serves as an Excessive Brightness Indicator. If the
bright light remains unchanged for over 10 seconds after the
indicator 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.

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. A red light
appears in the eyepiece to indicate that the IR illuminator is
operating.

You may focus IR light by placing the focusing lens of pivot
plate(B) onto the window of IR illuminator ( C).

SECTION V

ZEROING OPERATIONAL

DEFECTS

7

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. 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. Return the
ATN NVM-14 to the maintainer.

Figure 5-1

Shading

NOTE

Make sure the shading is not the result of improper eye-relief
adjustment.

8

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.

Figure 5-2

Mode Selector SwitchEdge Glow

9

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. However, some types of
blemishes can get worse over time and interfere with the ability
to perform the mission. If you believe a blemish is a cause for
rejection, record the specific nature of the problem on the main­tenance forms and identify the position of the blemish by using
the clock method and approximate distance from the center (e.g.,
5:00 toward the outside, 2:30 near the center, or 1:00 midway).

The following are cosmetic blemishes:

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 to the maintainer. 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 and the ability to per­form the mission.

10

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.

Figure 5-3

Bright Spots and Emission Points

3. Black Spots.

These are cosmetic blemishes in the image intensifier or dirt or
debris 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 operator’s 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.

Figure 5-4

Fixed Pattern Noise

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.
