CHAPTER 1:
GENERAL INFORMATION
1.1 Introduction:
This manual provides operation and field level
maintenance instructions for the DTNVG. It also
provides specifications and data on the performance of
the Binocular. To ensure the safety of the operator and
the correct operation of the Binocular it is
recommended that this manual is read carefully in its
entirety before any deployment or field application.
1.2 Equipment Description:
The DTNVG is a self-contained night vision
device that enables improved night vision using
ambient light from the night sky. Typically, the
moon, star and/or sky glow.
Optically, it is made up of two sets of objective lens,
image intensifier and eyepiece lens. The objective
lens collects light reflected from the night scene by
the moon, stars, or night sky, inverts the image and
focuses that image on the image intensifier. The
image intensifier converts the captured light into a
visible image and reinverts the image which can then
be viewed through the eyepiece lens.

2
In situations where there is no light at all the
unit can be switched into the infrared (IR) mode.
The DTNVG is equipped with an internal IR
LED enabling the unit to use this to the human
eye invisible light to operate.
The DTNVG is designed for differences in the
physical features of individuals. This allows for
a wide range of operators to use the system
safely and comfortably. Some of these design
features are the power switch, eye relief
adjustment, dioptre adjustment, and objective
focus. Lightweight and versatile, the DTNVG
can be hand-held, head-mounted, helmet-
mounted.
The DTNVG consists of two identical
Monoculars mounted to a body assembly. The
Monoculars may be pivoted sideways (when
pivoted outside the field of view, the monocular
will individually turn off.) When the DTNVG is
mounted to a helmet or head mont, the DTNVG
may be flipped up and temporarily stowed, the
DTNVG will automatically go into Standby
Mode turning off the Monoculars. The DTNVG
will automatically Turn On when flipped down
again. Each monocular is comprised of three
identical primary subassemblies: objective lens
assembly, monocular housing with image
intensifier assembly and eyepiece lens assembly.

CHAPTER 2:
PREPARATION FOR USE
2.1 Introduction:
This section contains instructions for installing and
attaching various components and accessories to the
DTNVG for operation under normal conditions.
2.2 Battery Precautions:
WARNING
Inspect batteries for bulging prior touse. I
f
thebatteryshowssigns of b ulging, do not
use.
WARNING
Do not heat, puncture, disassemble, short
circuit, incinerate, attempt to recharge or
otherwise tamper with the batteries. Turn
OFF the DTNVG if the battery compartment
becomes unduly hot. I
f possible, wait until the
batteries have cooled before removing them.
WARNING
Do not replace batteries in a potentially
explosive atmosphere. Contact sparking may
occur while installing or removing batteries and
cause an explosion. Failure to follow these
instructions could result in death or injury
.

8
2.3 Battery Installation:
Install one (1) AA or CR123A battery as follows.
1. Remove the battery cap by turning it counter-
clockwise.
2. Check to ensure the O-ring is present. If not,
replace it.
3. Observe polarity as indicated on the outside of
the battery compartment.
4. Insert battery into the battery compartment,
Minus (-) end first.
5. Replace battery cap by pushing and turning it
clockwise. Tighten it firmly to ensure a
watertight seal.

9
2.4 Eyecup Installation:
Perform the following procedure to install
eyecup onto the Binocular.
1. Carefully press the eyecup over the end of the
eyepiece lens. Rotate the eyecup into proper
viewing position. Adjust for best fit. The eyecup
must seal around your eye and prevent the green
glow from escaping.
2.5 Demist ShieldInstallation:
Perform the following procedures to install the demist
shield on the eyepiece lens.
1. Carefully remove the eyecup.
2. Carefully press the demist shield onto the
eyepiece. Be careful not to smudge the eyepiece
lens or demist shield.
3. Replace the eyecup.
CAUTION
If the demist shield is wiped while wet or with
wet lens tissue, you will damage the coating.
NOTE
If inclement operating conditions are expected to
exist (e.g. significant temperature change and
high humidity), install demist shield to minimize
eyepiece lens fog prior to execution of mission.

10
2.6 Sacrificial WindowInstallation:
Perform the following procedure to install the sacrificial
window onto the objective lens assembly.
CAUTION
If adverse operating conditions (blowing dust or
sand) are expected to exist, attach the sacrificial
window to protect the objective lens from
scratches or other damage.
PVS14 Lenses
1. If the objective lens cap is in place, remove it.
2. Carefully push the sacrificial window onto the
objective lens until it stops. Turn the
sacrificial window clockwise until it snaps
into place.
AN/VS Lenses
1. If the objective lens cap is in place, remove it.
2. Carefully push the sacrificial window rubber
housing onto the objective lens until it stops.

CHAPTER 3:
OPERATING INSTRUCTIONS
3.1 Introduction:
This chapter contains instructions for the safe
operation of the DTNVG under normal circumstances
and environments.
3.2 Controls and Indicators:
The DTNVG is designed to adjust for different users
and corrects for most differences in eyesight. The
controls and indicators for the DTNVG are shown in
Figure 3-1 and are described in Table 3-1.
CAUTION
The DTNVG requires some ambient (moonlight,
starlight, or artificial light, etc.) to operate. The
level
of performance depends on the level of
light.
Night light is reduced by passing cloud cover, while
operating under
trees, in building shadows, etc.
The DTNVG is less effective viewing
into shadows
and other darkened areas.
The DTNVG is less effective through rain, fog,
sleet, snow, smoke, and other reflective material.
