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 objec-
tive 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.
a
NOTES
• When utilizing the ATN NVM-14 for driving purposes, the gog-
gles 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 bat-
teries 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 pre-
cautions.
• 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.

B. MECHANICAL FUNCTIONS
The mechanical functions of the ATN NVM-14 allow for dif-
ferences 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 Pro-
cedures – Headmount Adjustments), diopter adjustment, and
objective lens focus. These mechanical controls are identi-
fied in Figure 4-3.

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. How-
ever, 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.
Push and turn the On/Off/On IR switch knob to the On IR
position, observing that a red light appears in the eyepiece to
indicate that the IR illuminator is operating.
4-6
5-1
Operational defects relate to the reliability of the image intensi-
fier 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 opera-
tion.
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.
5-2
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
5-3
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 blem-
ishes can get worse over time and interfere with the ability to per-
form the mission. If you believe a blemish is a cause for rejec-
tion, record the specific nature of the problem on the mainte-
nance 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 view-
ing. Bright spots are acceptable if they do not interfere
with the ability to view the outside scene and the ability to
perform the mission.
5-4
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.
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 inter-
fere with the operator’s ability to perform the mission.
5-5
4. Fixed-Pattern Noise
This is usually a cosmetic blemish characterized by a faint hex-
agonal (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
5-6
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.
