5. OPERATION INSTRUCTIONS
Installing battery
Unit is supplied without a battery installed.
Prior to installing the battery, make sure the On/Off/IR/Auto
switch (1, Fig.1) is in the OFF position and the objective lens
cap is on.
The Unit can operate on either a single AA or CR-123 lithium
battery. Lithium batteries hold a charge longer than conventional
batteries and provide better performance at low temperatures.
To install a battery remove the battery compartment cover (6,
Fig.1) by rotating it counter clockwise. When using a CR-123
lithium battery, remove the battery bushing located under the
battery compartment cover by rotating it counter clockwise.
Store the bushing in a safe place while not in use. Make sure the
battery is installed with the correct polarity as indicated on the
housing. Insert the battery and replace the battery cover.
Activating the Unit
In daylight ensure the objective lens cap is in place prior
to activating the Unit.
To check if the Unit is operational switch it ON by rotating the
On/Off/IR/Auto switch clockwise while looking through the
eyepiece (4, Fig.1). You should see either a green or black and
white image (depending on the model you have purchased). If
9

the screen is not lit ensure the batteries installed are charged
and the polarity is correct.
When the Unit is ON you may see a
red and/or yellow LED indicator in
the field of view (Fig. 2). When the
yellow or red LED indicators are
flashing, the remaining battery
power is low and it should be
changed. For uninterrupted operation
keep a fresh battery ready and
replace it on time. If the red LED
indicator is lit solidly, the IR
illuminator is activated. This
warning is intended to prevent the
user from unintentionally giving
FIGURE 2
IR illuminator indicator (red,
left), Low battery indicator
(yellow, right)
away their position.
In the daytime with the objective lens cap on, it is normal to
observe a ‘fuzzy’ image. Switching on the Unit in the daytime is
intended for testing purposes only. During night use, the
objective lens cap should be removed and the ‘fuzzy’ image
should no longer be observed.
The rotating switch has four positions: “Off”, “Auto”, “On”,
“IR”. In Auto mode the monocular will switch off automatically
when turned upright. This mode saves battery life and avoids
unintentionally illuminating the users face during combat
operations.

Switching the Unit off
After you have finished using the Unit, turn it off by rotating the
On/Off/IR/Auto switch to the ‘OFF’ position. Replace the
objective lens cap. If storing the unit for an extended period,
remove batteries. Place Unit in appropriate storage container.
Adjusting to individual vision
Turn on the Unit. Direct the Unit at an object placed within 8-15
m from the viewer. While looking through the Unit at the object,
first rotate the diopter adjustment ring on the eyepiece (4, Fig. 1).
Once focus is nearly achieved, rotate the objective lens (3, Fig. 1)
to achieve final focus.
5.1
Manual gain adjustment
Each NVS 14 series device is equipped with a manual gain
adjustment system (9, Fig. 1). This system allows the user to
adjust the gain (or light amplification) of the Unit in accordance
with the prevailing light conditions.
The manual gain system allows for the gain of the Unit to be set
between 20% and 100%. In relatively dark situations, the gain
should be set high enough that the user can see a clear, well-lit
image in the eyepiece. In relatively bright conditions, the gain
should be reduced to avoid an overly brightened image from
being displayed in the eyepiece.
11
Download from Www.Somanuals.com. All Manuals Search And Download.
Auto shut OFF at bright light
Each unit has a built-in high light sensor located near the IR
illuminator (2, Fig. 1). This sensor shuts the monocular off after
about 45 seconds of exposure to light exceeding 10-1 lux.
To reset the monocular switch it off and then back on as
described in 6.3 and 6.2.
High-light shut-off feature does not mean that the Unit will react
to occasional flashes or bright spots. It protects the tube against
excessive light exposure only in order to avoid permanent
damage.
Auto-gating system
The NVS 14-3AG and NVS 14-3AGBW variants contain, in
addition to the systems described above, an auto-gated power
supply. This system automatically controls the power supplied to
the IIT in changing lighting conditions. This serves not only to
protect the IIT from exposure to bright lighting sources, but also
to automatically provide the user with the optimal image
regardless of prevailing light condition.

Using the Unit with headgear or helmet
The Unit is supplied with headgear designed to allow the
mounting of the Unit on the head. Prior to using the headgear
adjust its straps so that the headgear fits the head comfortably but
firmly and does not slide off during movement.
The Unit is attached to the headgear with a swing arm mount (1,
Fig. 3). To attach the arm mount to the headgear loosen the
tightening screw on headgear, slide helmet groove (2, Fig. 3)
onto the rail, and then tighten the screw.
To attach monocular to the arm turn the knob (3, Fig. 3), slide the
arm groove (4, Fig.3) along the dovetail platform of the
monocular (8, Fig. 1), and then release the knob.

To set comfortable eye-relief (the distance between your eye and
the eyepiece), loosen tightening screw on the headgear and move
the Unit, then tighten the locking screw.
To use the Unit with PASGT head and helmet mount unscrew
the grooved pad (2, Fig. 3) from the swing arm mount and screw
on the US type clip (6, Fig. 3) using four screws (Fig. 3) instead.
US type helmet clip is optional and must be ordered seperately.
To switch between left and right eye, press the flip button (5, Fig.
3) on the mount and rotate it respectively until you hear an
audible click.
Swinging head mounted Unit for unobstructed view
When the head mounted Unit is not in use you can raise it to
clear the view without taking the headgear off by using the
“flip/flop” feature. To swing the Unit from the view press the
button (5, Fig. 3) and raise the device until you hear a click.
In “Auto” position of the switch, the monocular will turn off
automatically. Reverse the operation to return the Unit to
working position.
Using IR illuminator
In case of insufficient light when observing a close object turn on
the IR illuminator by turning the On/Off/IR/Auto switch.
Red indicator visible through the eyepiece will warn you when
the IR illuminator is on.
Note: The IR illuminator is visible to anybody equipped with a
night vision device and can disclose the user’s presence.

To attach the 5x or 8x add-on lenses, follow the following
procedure:
1. Make sure the Unit is off.
2. Remove the objective lens cap.
15
Download from Www.Somanuals.com. All Manuals Search And Download.
3. To detach the current lens: hold the lens by its base and
rotate it counter-clockwise. Once the lens has been
removed, store it in a safe, clean space.
4. To attach desired lens: rotate it clockwise along the
threading until snug—do not overtighten.
The threads are very fine (to prevent humidity penetration) and
can be damaged easily. Do not apply force when rotating the
lens. If the desired lens does not rotate smoothly along the
threading, make sure that the threads are aligned.
The Unit is ready for operation immediately after the lens
change. During operation in brightly lit spaces, ensure the
objective lens cap is in place.
Demist shield and sacrificial window
Note: Demist Shield and Sacrificial Window are optional.
The sacrificial window protects the objective lens from sand,
dust and other objects that can scratch or otherwise damage the
lens. The sacrificial window is affixed on the objective lens in
place of the tinted objective lens cap which comes installed on
the Unit.
The demist shield filter protects the eyepiece against fogging. To
install it fold the eyecup down, in order to access the thread, and
screw the filter gently onto the eyepiece.

Camera / Video adapter
If our adapter does not fit your camera from a camera supply
store, obtain proper step up / step down rings.
Using the helmet mount
The Unit can be equipped with an optional NVS H Mount
which fits a variety of existing helmet models.
The Unit is fixed to the mount via a locking screw (1, Fig.
6). To adjust the position of the Unit to your eye level, use
the mount binding screw (4, Fig. 6). To adjust the eye
relief first loosen locking screw and set a comfortable
distance between the eyes and the eyepiece; then tighten
the locking screw.
The Unit can be fixed in three predetermined positions: vertical,
horizontal, and 15-20° above horizontal. Although the relative
angles between these positions cannot be changed, the starting
point can be adjusted using the flip-up adjustment screws (3, Fig.
6). If you loosen them, you can rotate the flip-up mechanism to
17

The NVS W Mount is affixed to the Unit and the Picatinny rail
using oversized, easy to tighten screws. The NVS QR Mount is a
‘quick release’ mount that utilized a lever for affixing to and
removing from the Picatinny rail.
Using with a daytime riflescope
Although the Unit does not contain a reticle
and thus cannot be used as a standalone
riflescope, it can be mounted inline with a
magnified daytime or red dot holographic
sight enabling night time use.
This can be accomplished either by
mounting the Unit in-line of the day sight
using the NVS W or QR mount or utilizing
the optional NVS Coupler (Fig. 9) to mount

6. TROUBLESHOOTING
No green (or black and white) image visible
Check that the batteries are installed properly and are full
charged. Wrongly installed and expended batteries are
the most common problems leading users to believe their
Unit is defective.
Image is unclear
Check if the lenses are foggy or dusty. Clean them if necessary.
If the image is still unfocused – adjust the diopter correction of
the eyepieces. The image will always be unclear when the
objective lens cap is in place. The unit is designed to provide a
clear image in dark condition in which the objective lens cap is
not required.
Image flashes
Image may flash during the first two minutes after activation. It
may continue flashing if exposed to bright light (even with the
lens cap on).
Condensation accumulates on Unit
When the Unit is moved from cold to warm environments
internal condensation may appear. If this occurs, the Unit must
be warmed up for up to two hours in order to regain full
operational capacity.
21

Visibility decreased or disappeared
Bright light sources (the Moon, projectors or headlights) may
cause visibility to degrade or even completely disappear. Move
the device away from the light source immediately. The image
will be restored within two minutes.
Adverse atmospheric conditions such as fog, haze or extremely
dark environments will decrease visibility.
