The NVB5 is a powerful night vision bi-ocular. They are waterproof and can withstand the
rigors of almost any environment. The NVB will give you the range and clarity that other
bi-oculars simply can not touch.
The NVB5X have a built in IR for total darkness with indicator “ON” light within the FOV.
The NVB5X is available with a wide range of image intensifier options to meet a wide array
of specification requirements.
The NVB5X is a complex opticoelectronic system for individual use. The device consists of the objective lens assembly, eyepiece and the body. The body contains a image
intensifier tube assembly with an integrated high voltage power source and the battery
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.
Diopter adjustment
• Take the NVB5X 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 .
Lens focus adjustment
• Press the button (short press - less than 1.5
sec.) to turn the unit on by 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
• 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, push the button again by short press (less than 1.5 sec.).
To focus the NVB5X, 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 NVB5X
while remaining almost totally invisible to the
naked eye.
The NVB5X goggles have a built in IR with indicator “ON” light within the FOV. To turn the
IR on, push the button by long press (more
Built-in IR illuminator
than 1.5 sec.). 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 effectiveness over a great distance.
To turn the IR off, push the button again by long press (more than 1.5 sec.).
NOTE: The IR will automatically turn off when the unit’s power is turned off.
450 mw infra-red illuminator
The 450 mW IR Illuminator is powered
by a separate from the main unit battery. To install the battery unscrew
the cap and insert a battery the way
shown at the diagram on the IR.
To install the 450mW IR Illuminator
onto the bi-ocular loosen the clamp
of IR Illuminator, insert his rail into
the bracket of bi-ocular and screw the

IR Focusing
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 from the kit
should be used for weakening the clamp located on the IR. Rotate the IR placing it in the
most convenient position. Tighten the clamp with the screw-tool to fix the new position.
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 NVB5X 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 NVB5X 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.
• 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.
