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:

b
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.

1.2. DESCRIPTION AND DATA
1.2.1. DESCRIPTION
A. Purpose
The PS-22 is an effective night vision system that mounts forward
of an existing riflescope/spotting scope (further referred to as a
scope) adding night vision capabilities to daytime target acquisi-
tion platform. Advisable dayscope magnification is 1X to 6X (2.5X
to 4X is optimum). The sight is installed and removed without af-
fecting boresight (permanent boresight alignment).
NOTE
The PS-22 can be installed also forward of viewfinders of va-
rious instruments to widen operating illumination range.
B. Principle of Operation
The PS-22 operation is based on the principle of electron-optical
intensification of light. The input fast catadioptric lens collects
available ambient light from source such as the moon, stars and
skyglow and focuses it on the image intensifier tube photocath-
ode. The tube amplifies the light and produces the viewable im-
age projected by the output lens from the tube screen into the
dayscope lens. Thus the sight provides the capability for operator
to see through the scope at night.
C. Features
The PS-22 has the following important features:
• Available with 2+, CGT, HPT or 3rd generation image intensi-
fier tube.
• Powered by a single CR 123A battery.
• Adjusts for lens focus.
• Is mounted on MIL-STD-1913/Picatinny rail or dayscope lens.
• Equipped with remote control.
• Automatic Brightness Control System always keeps the IIT
brightness level constant, even under unsteady brightness
conditions.

1-6
NOTE
Automatic Brightness Control System do not protect a device
from damage by bright light sources (a fire, headlights of the
automobile, lanterns, etc.). Do not point the device at a bright
light source.
• Is submersible to 10 m for 30 minutes.
• Filled with dry nitrogen to prevent internal fogging.
D. System Limitations
The PS-22 is an effective night vision system designed for night
operations but does have following limitations:
• The sight requires some night light (moonlight, starlight, etc.)
to operate. Night light is reduced by such factors as passing
cloud cover and objects that produce shadows.
• The sight is less effective viewing through rain, fog, sleet,
snow, smoke.
• Under starlight conditions low contrast environments (such as
snow-covered territory, sandy deserts, large bodies of water or
grassy hills) degrade visibility thereby disguising or masking
changes in terrain.
• Under too low-light conditions the sight looses some of the
resolution that it has under full moon.

2.1. INSTALLATION PROCEDURES
2.1.1. BATTERY INSTALLATION
CAUTION
Ensure the function switch
is in the off position before
installing a battery.
Install the battery as follows:
1. Unscrew the battery com-
partment cap.
2. Install the battery into the
battery compartment. Fol-
low battery symbol on the
sight body (Figure 2-1).
3. Replace the battery com-
partment cap.
2.1.2. INSTALLATION ON MIL-STD-1913/
PICATINNY RAIL
NOTE
The optical axis of the PS-22 and the riflescope should be
matched. Difference of the axes position more than 3 mm is
not recommended. Measure the height of the riflescope axis
above the rail. Observe Table 1-2 for the sight axis height above
the rail. If the difference in the axis heights of the PS-22 and rif-
lescope is more than 3 mm it is necessary to replace riflescope
mounting rings or monoblock by proper ones.
Install the PS-22 on MIL-STD-1913 rail as follows:
1. Take off the output lens cap (Figure 1-1, 4) and put it into the
storage case.
2. Remove the light suppressor from the storage case. Put it on in
place of the out put lens cap.
3. To open the sight Quick Release Mount , slide the cam latch for-
ward (Figure 2-2, arrow A) and turn the cam backward (arrow B).
4. Place the sight onto MIL-STD-1913 rail. Be sure to engage the
recoil lug into the groove on the top mounting surface of the
FIGURE 2-1.
