• Do not test the device in daylight conditions for more than ten (10)
minutes, even with the daylight filter/ lens cap on.

• The purpose of the built-in IR illuminator is to provide additional
illumination when necessary while viewing scenes at close distances
(up to 3 meters).

• Only use the attachments/accessories specified by the manufacturer

• All service must be provided by the manufacturer

WARNING:

• DO NOT DISASSEMBLE THE DEVICE.
Disassembly can cause permanent damage.

• Use of the BNVD in brightly light conditions and in the places with
bright light sources such as firelight, headlights, searchlights, etc.
can damage the unit’s intensifier tubes. Avoid exposing the unit to
these types of light sources.

• When operating the device in extremely dark conditions, the light
from the unit’s IR illuminator will be invisible to the unaided eye.
However, the light can be detected by other night vision devices
(NVD).

• To reduce the risk of detection by another NVD, avoid prolonged
activation of the IR illuminator.

• The IR light is more easily detected by an NVD when used in smoke,
fog and rain. Avoid prolonged activation of the unit’s IR illuminator in
these conditions.

• The equipment requires some ambient light (moonlight, starlight,
etc.) to operate.

• Performance of the device in nighttime conditions depends on the
level of ambient light in the environment. Please remember the
following:

- The level of ambient light is reduced by the presence of clouds,
shade, or objects that block natural light (trees, buildings, etc.).

- The equipment is less effective when operated in shadows and
other darkened areas.

- The equipment is less effective when operated in rain, fog, sleet,
snow, dust or smoke.

- The equipment will not “see” through dense smoke.

USER MANUAL

SECTION 1. INTRODUCTION

1.1 BINOCULARS

This manual covers the BNVD night vision binoculars and all applicable
components. It is recommended that you read and understand this
manual to optimize the binoculars operation.

1.2 INTRODUCTION

The BNVD is a hand-held, head-mounted or helmet-mounted night
vision system that enables mobility, driving, weapon firing, short-range
surveillance, map reading, vehicle maintenance and administering first
aid during operation in both moonlight and starlight.

The BNVD is a dual-channel night vision device. The BNVD uses
advanced, multi-coated optics and a tough, compact, and ergonomic
composite housing. The BNVD can be used as a monocular or binocular
goggles, or stowed out of the way without removing. Rotating binocular
design allows low profile against helmet when in stowed position. This
device operates with a single gain control knob and utilizes features
like a flip up turn off with flip down turn back on function, when used
in conjunction with a compatible head/ helmet mount. There is also an
integral infrared illuminator for reading a map.

1.3 FEATURES

1.5 IMAGE INTENSIFIED NIGHT VISION

VERSUS INFRARED THERMAL VISION

Image Intensification “I2” works by collecting tiny amounts of light,
including the lower portion of the infrared light spectrum, that are
present but may be imperceptible to our eyes, and amplifying it to the
point that we can easily observe the image.

Thermal imagingtechnology operates by capturing the upper portion of
the infrared light spectrum, which is emitted as heat by objects instead
of simply reflected as light. Hotter objects, such as warm bodies, emit
more of this light than cooler objects, like trees or buildings.

The thermal vision device makes images from heat, not light, a feat
impossible for the naked eye or image intensified (I
devices. This allows you to see clearly without any visible light. People,
animals, and objects all generate or reflect heat, and are clearly seen
by the thermal vision device, in even the most adverse conditions.

Thermal is best used to detect the desired object. It is the best 24-hour
imaging option.

Night vision devices provide a more natural image, wider field of view
(FOV), wider operating temperature, and longer battery life.

SECTION 3. OPERATING THE SYSTEM

3.1 SYSTEM DESCRIPTION

The BNVD utilizes the principle of intensification of the residual light
that is reflected from the surrounding objects. The optical system of the
unit consists of two monocular channels, each consisting of a lens, an
image intensifier tube (IIT), and an eyepiece.

This device operates with a single gain control knob for both channels.
Each unit allows for vertical adjustment (using the head or helmet
mount), fore-and-aft adjustment, objective lens focus, eyepiece focus,
and interpupillary distance adjustment. The binoculars are equipped
with an infrared (IR) light-emitting diode (or illuminator) to provide
additional illumination for reading a map. The binoculars are also
equipped a low battery indicator, a bright light cut-off system indicator,
and IR illuminator indicator in the field of view of device.

SECTION 4. MAINTENANCE

4.1 BATTERY REMOVAL AND
REPLACEMENT

Refer to Part 2.2 for battery installation procedures.

4.2 CLEANING THE BNVD

Wipe the housing with a damp cloth as needed.

CAUTION: Do not use abrasives or solvents to clean the housing, lens,
or display window. Do not use ammonia-based cleaning products to
clean the lens. Doing so may damage the anti-reflective coating of the
lens.

The BNVD lens is designed for the harsh outdoor environment and has
a coating for durability and anti-reflection, but it may require cleaning
occasionally. Avoid scratching the lens and/or leaving fingerprints on
the optics. Optics can be damaged by improper cleaning. Clean the lens
according to the instructions below when image quality degradation is
noticed or excessive dirt or other contaminant is on the lens.

Do not use abrasive materials, such as paper or scrub brushes as this
will possibly damage the lens by scratching it. Only wipe the lens clean
when there is visible contamination on the surface.

PREFERRED METHOD FOR CLEANING THE LENS

Materials:

• Optical-grade cloth

• Pure water (de-ionized or other)

• Isopropyl alcohol (IPA)

Saturate a piece of the lens tissue with the water and drape it over
the lens. Let the surface tension of the water pull the tissue onto the
lens surface and then drag the tissue across the lens surface. Repeat
several times with different pieces of tissue.

Repeat the same step using IPA instead of water. Drag the final piece
of tissue over the lens several times to prevent pooling, which could
leave a residue behind.
