APPLICATION
device consists of (see above figure) the objective lens assembly, eyepiece and the body. The
body contains a 1st Gen.+ image intensifier tube assembly with an integrated high voltage
power source and the three volt battery housing. When installing the battery one should keep
in mind that the polarity of the battery should coincide with the diagram on the body next to the
battery housing cap.
Objective lens protective cover (not shown) 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 situations. 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.
The device is powered up by sliding the switch on the rear of the unit labeled “PWR”. You may
notice a persistent green glow for up to five (5) minutes after you have turned the unit off. This
is normal for the 1st Gen. light intensifier tube.
OPERATION
• Take the monocular out of the case.
• Install the battery into the housing with the polarity order as shown on the scope. Battery
Type: 3 Volt Lithium, #CR123A .
• Slide the switch to turn the unit on with the protective 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.
FOCUSING
To focus the Viper, first you will need to adjust the diopter. Simply turn the
diopter clockwise until it stops. Then, while looking throught the diopter at
an object, slowly turn the diopter back counter 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 conditions 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 Viper while remaining almost
totally invisible to the naked eye. The IR illuminator on the Viper is located
underneath the front lens, next to the battery compartment.
When you turn the scope on the IR will automatically turn on. It is impor-
tant to remember that the IR illuminator is simply an infra red light source,
and like any light source, it may loose its effectiveness over a great dis-
tance.
NOTE: The IR will automatically turn off when the unit’s main power switch is turned off.
USING THE 4X TO 8X DOUBLER
(optional)
Unscrew 35 mm lens off the body of the Viper (make sure that the unit is turned off). Screw the
doubler into the body of the Viper where the 35 mm lens was removed. Screw the 35 mm lens
or your 90 mm lens into the doubler.
NOTE: You can also add just the 90mm lens to a Viper without a doubler.
NOTE: When attaching the doubler do not be afraid to use a little force.

USING THE CAMERA ADAPTER
(optional)
To use your Viper 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 Viper
• 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 Viper’s eyepiece.
• Tighten the three set screws to fit snugly to the Viper’s eyepiece
3
• You may need to focus the 35mm camera or video camera in combination with the Viper in
order to get the sharpest possible image.
• We suggest that you find an open space to work in. Focus the Viper so that the scene is at
its sharpest. For best results you should disable the auto focus (if any) on either the 35mm
camera or the video camera and manually focus the 35mm camera or the video camera.
Once the image is sharp, then simply adjust the Viper’s front lens to change the focus.
• An important part to remember is that you are not taking a picture of an object that is far away
from you, but you are actually taking a picture of the phosphorous screen of the Viper that is
only 2-3 inches away.

HEADGEAR
PART I
1)Thefirststepthatyouwanttotakeinmount-
ing your VIPER on your head is to fit the head-
gear to your size. Adjust the headgear fist
befor attaching the VIPER to it.
Figure H1
2) Loosen all the straps and plase the head-
gear on your head.
3) You will want to tighten the side straps
(Figure H1) fist.
Figure H3
4) Then secure the top strep (Figure H2).
This one is rather tight so you might need
to remove it from your head, when you are
adjusting the strap.

5) And last you will want to adjust your chin
strap (Figure H3).
PART II
Now you are ready to mount the VIPER on to your headgear.
1) Remove the already adjausted headgear from your head.
2) Slide the VIPER on to the rail (Figure H4). Loosen the tightening
knob (on the rail) to enable you to easily slide
the unit on. Don’t retighten the knob just yet.
3) Adjust the vertical position of the VIPER to

your comfort and tighten the vertical tigten-
ing screw (Figure H5, #1) and tighten vertical
fixator (Figure H5,#2).

CLEANING THE EYEPIECE
You may need to clean the eyepiece of the Viper from time to time in order to guarantee top
performance. When you receive your Viper you should check for dust on the eyepiece of the
unit.
First you will need to remove the eyepiece. To do that you will need to initially loosen the 2
set screws that can be found on the base. Then unscrew the eyepiece counter-clockwise to
remove it.
NOTE: You do not have to remove the set screws completely, they are very small and easy to
misplace.
CAUTION: Use only Photographic lens cleaning tissue on these surfaces. Be careful not to
scratch or smudge any of these surfaces. When using compressed air to blow dust away, make
sure to avoid inverting the can while spraying. This can cause frozen propellant to exit the can,
which can cause serious problems with the glass and phosphor screen.
STORAGE AND CARE
• If the device is not to be used for extended period of time (more than 10 days) remove the
battery.
• Avoid touching lenses. If fingerprints or traces of dirt or dust appear, clean their surface with
a Photographic lens cleaning tissue.
• Keep lens cap/daylight filter on when not in use.
• The Viper is not harmful to the user or the environment.
• Do not disassemble except to clean the front lens and eyepiece: it will void your warranty.
• Evaluate the scope function by looking through it in a lit environment with the daylight filter
lens cap on. Never use in daylight without the daylight filter lens cap on.
• Never point the Viper at a bright light source.
• Adverse atmospheric conditions such as fog, smog, or haze and a lack of ambient light
(moon or starlight) may diminish the effective viewing distance.
TROUBLE SHOOTING
Q: Flashes, flickers, or clicking occur while operating
S: If it occurs within the first five minutes of inserting new batteries, it is normal and the device
will resume normal operation soon thereafter. If it occurs for more than 10 minutes, contact for
service instructions.
Q: Dark spots on screen.
S: These are either cosmetic blemishes in the intensifier tube or dust particles.
Q: Screen becomes darker than at previous use.
S: Replace batteries. If problem persists, contact your dealer or other authorized service rep-
resentative for service instructions.
Q: Image not clear.
S: Adjust objective lens, and/or the eyepiece.
