SAFETY SUMMARY
CAUTIONS
• The ATN PS-22 is a precision optical instrument and must be han-
dled carefully at all times to prevent 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 objective
lens when the sight is not in use or when checked out in daylight
conditions.
• The IR illuminator is the 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 others 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.
WARNING
Do not carry batteries in pockets containing metal objects such as
coins, keys, etc. Metal objects can cause the batteries to short cir-
cuit and become very hot.
THIS PRODUCT CONTAINS NATURAL RUBBER LATEX
WHICH MAY CAUSE ALLERGIC REACTIONS.
CAUTION:

WARNING
Toxic Material
The image intensifier’s phosphor screen contains toxic materi-
als.
• If an image intensifier breaks, be extremely careful to avoid
inhaling the phosphor screen material. Do not allow the mate-
rial to come in contact with the mouth or open wounds on the
skin.
• If the phosphor screen material contacts your skin, wash it off
immediately with soap and water.
• If you inhale/swallow any phosphor screen material, drink a lot
of water, induce vomiting, and seek medical attention as soon
as possible.
WARNING
Do not use contaminated light suppressor. They must be
replaced.

c
EQUIPMENT LIMITATIONS
To avoid physical and equipment damage when using the
ATN PS-22, 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.
