APPLICATION
The PS-23 Night Vision goggles is one of the most versatile night vision devices available. This unit
can be handheld, head-mounted for hands free usage, it is camera/ camcorder adaptable, and can
be 3x binocular. The intergrated IR illuminator enhances the ability of the user to read maps and oper-
ate in confined, zero light areas. The PS-23 is available with several image intensifier options to meet
a wide array of specification requirements.
The PS-23 night vision goggles is a complex opticoelectronic system for individual use. The device
consists of the objective lens assembly, eyepiece and the body. The body contains an image inten-
sifier tubes assembly with an integrated high voltage power source and the battery housing.
Objective lens protective cover is intended to protect the objective lens from dust and scratches. It
also will act as a daylight filter, allowing you to test the scope in daylight or other bright light situa-
tions. The pinhole in the center of the protective cover allows the user to check the operation ability
of the device in daylight conditions.
NOTE: Do not test the scope in daylight conditions even with the daylight filter/lens cap on for more
than ten (10) minutes.
OPERATION
• Take the goggles out of the case.
• Install the battery(3 Volt, CR123A) into the housing with the polarity order as shown on the scope.
• Rotate the operation knob from “OFF” position to “ON” position to turn the unit on. The protec-
tive lens cover still attached to the lens. Do not turn the unit on in the daytime without the
protective lens cap on. You should see green glow in the eyepiece.
• Observe the scene and adjust the diopter for optimal image clarity.
• You may now enter a dark environment or simply shut the lights off in order to darken the room.
• Next, remove the lens cap/daylight filter. Adjust the front lens for the distance of the focus. You
should not have to readjust the diopter.
• To turn the unit off, rotate the operation knob from “ON” position to “OFF” position.
FOCUSING
To focus the PS-23, first you will
need to adjust the diopter. Simply
turn the diopter clockwise until
it stops. Then, while looking
through the diopter at an object,
slowly turn the diopter back coun-
ter clockwise until the grain in the
image is sharp.

NOTE: We suggest that you focus the diopter during daylight with the filter on.
Next focus the front lens until the image and the grain are both sharp. When you are in low-light con-
ditions and the daylight filter is off, you may focus the front lens to receive sharp image, the diopter
should not be adjusted.
NOTE: The front lens should be readjusted as you view objects at different distances.
INFRA-RED ILLUMINATOR
Infra-red illuminators, or IR illuminators, are common to night vision.
The IR light greatly enhances the performance of the PS-23 while
remaining almost totally invisible to the naked eye.
To turn the IR on, draw and rotate the operation knob to “IR” posi-
tion.
It is important to remember that the IR illuminator is simply an infra
red light source, and like any light source, it may loose its effective-
ness over a great distance.
FLIP-UP HEADSET
FITTING THE HEADGEAR
1) Fit the head gear to your head size. Adjust the head
gear fist before attaching the PS-23 to it.
2) Loosen all the straps and place the head gear onyour
head.
3) Tighten the straps until the head gear fits firmly.
GOOGLES INSTALLATION AND AJUSTMENT
Now you are ready to mount the PS-23 on to your
headgear.
1) Remove the already adjusted head gear from your
head.
2) Push button [1] and insert the bracket [2] of the PS-23
to the rail of the headset.
3) Place the head gear with PS-23 onto your head.
4) Loosen the screw [3] and move the unit along the rail
for eye relief adjustment .
The PS-23 headset has a flip-up mechanism. Push the
button [4] on the side of mount and lift the unit up until the
unit fixates in the top position.
Push same button to lower PS-23 to viewing position.
PROTECTIVE SYSTEM
The automatic highlight protective system analyzes light exposure with the sensor . If the level of
light exposure exceeds allowable the red indicator will turn on. If high light exposure is kept more
than 10 seconds the device automatically will off. If you move the unit away from the bright light
after it shuts off the unit will turn back on. If short-term actuation of a sight in a highlight condition(for
check of serviceability)is necessary the sensor should be closed by a cover.
NOTE: The automatic highlight protective system and automatic brightness control system do not
protect a sight from damage by bright light sources (a fire, headlights of the automobile, lanterns,
etc.). Do not point the device at a bright light source.

AUTOMATIC SHUT-OFF SYSTEM
The automatic shut-off system turn the power off when the device is upright on the flip-up headset.
When device is returned into the working position the system turn the power on again.
450 MW INFRA-RED ILLUMINATOR ( O P T I O N A L)
The 450 mW IR Illuminator works on a separate
battery from the main unit. To install the battery
unscrew cap and insert battery in the same direc-
tion as depicted by the diagram on the IR. To in-
stall the 450mW IR Illuminator to the scope screw
the adapter into the thread on the scope. Install IR
to the rail of adapter and screw fixator.
The IR illuminator control buttons are located on
its side. To switch the Digital IR illuminator on/off
press “+” and “-” buttons simultaneously. When
the IR illuminator is switched on you can see the
green LED lit. By pushing the buttons “+” and “-”
you may adjust the IR brightness.
The IR beam is focusable to change the field of
coverage. To change the beam width slightly turn the IR lens.
You could change the IR control panel fitting your needs. The screw-tool included into the set should
be used for weakening the fixing screw located on the IR. Rotate the IR placing it in the most conven-
ient position. Tighten the screw with the screw-tool to fix the new position.
For installation IR450 use adapter with Picatinny rail. Mount the adapt
3X LENSES ( O P T I O N A L)
The additional 3X Afocal Lenses a for PS-23 transform it to 3X binocular.
To install 3X Afocal Lenses screw it on the front lens of PS-23.
CAMERA ADAPTER ( O P T I O N A L )
To use your PS-23 with a 35mm camera or camcorder you will need the following:
1) If you plan to use a camcorder then your camcorder must have a MACRO feature. Most modern
camcorders today have a MACRO feature built-in.
2) If you plan to use a 35mm camera, you will need a MACRO lens. If you don’t have one, we advise
that you contact your local camera store.
3) You may or may not need a STEP-UP or STEP-DOWN ring in order to adapt the camera adapter
to your lens.
NOTE: The camera adapter comes with 37mm and 52mm threads. If you
need other sizes your local camera store should be able to help.
• Remove the rubber eyecup from the PS-23
• Screw the camera adapter onto the front of the lens on your Video camera’s
lens or your 35mm camera’s lens.
• Loosen the three set screws on the camera adapter.
• Place the camera adapter over the PS-23’s eyepiece.
• Tighten the three set screws to fit snugly to the PS-23’s eyepiece
