SAFETY SUMMARY
CAUTIONS
• The ATN PVS-7 is a precision optical instrument and should be
handled carefully to prevent its damage.
• Do not scratch the external lens surfaces or touch them with your
fingers.
• To protect the image intensifier, keep the lens cap on the objec-
tive lens on when the device is not in use or when it is checked out
in daylight conditions.
• The IR illuminator produces a light that is invisible to a naked
eye for use in conditions of extreme darkness. However, this IR
light can be detected by somebody else who use a night vision
device.
• If you use the rubber eyecups for a long time period, you may
suffer from skin inflammation. If you find any symptoms, consult a
doctor immediately.
This producT conTains naTur al rubber laTex which
may cause allergic reacTions.
CAUTION:

b
NOTES
• Do not test the device in daylight conditions even with the day-
light filter/lens cap on for more than ten (10) minutes.
• To protect the device from damage do not direct it to the bright
light sources (a fire, headlights of the automobile, lanterns, etc.).
• The purpose of the built-in IR illuminator is to view at close dis-
tances up to 3 meters when additional illumination is needed.
• The unit is equipped with the Automatic Shut-off System. This
system tracks when the unit is not used (the controls are not
touched for 60 minutes continuous) and shuts the unit off auto-
matically.
To turn the unit on after automatic shut off, you need to rotate the
operation knob to the OFF position first and then to the ON posi-
tion.

c
EQUIPMENT LIMITATIONS
To avoid physical and equipment damage when using the
ATN PVS-7, carefully read and understand the following equip-
ment limitations.
• The equipment requires some night light (moonlight, starlight,
etc.) to operate. The level of equipment performance depends
upon the level of light.
• Night light reduces by passing through the clouds, while operat-
ing under trees, at building shadows, etc.
• The equipment is less effective when viewing into shadows and
other darkened areas.
• The equipment is less effective when viewing through the rain,
fog, sleet, snow or smoke.
• The equipment will not “see” through the dense smoke.

1-3 GLOSSARY
BLACK SPOTS. These arc cosmetic blemishes in the image in-
tensifier of the PVS-7 or dirt or debris between the lenses.
BRIGHT SPOTS. These can be defects in the image area pro-
duced by the PVS-7 . This condition is caused by a flaw in the film
on the micro-channel plate. A bright spot is a small, non-uniform,
bright area that may flicker or appear constant. Bright spots usu-
ally go away when the light is blocked out and arc cosmetic blem-
ishes that are signal induced.
BROWPADS. Three hook-and-pile browpads are provided to ad-
just the head mount to fit different head sizes. The thin brow pad
(fits on a large head) comes attached to the head mount and the
thick or medium (fits on a smaller head) brow pads are stored in
the carrying case.
