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 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.
• 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.

b
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.

c
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.
