6. OPERATION INSTRUCTIONS
6.1
Installing battery
Unit is supplied with uninstalled battery.
Prior to installing the battery, make sure the switch (1, Fig.1) is
in the OFF position and the lens cap is on.
The unit can operate on either AA Alkaline or CR-123 Lithium
battery. Lithium battery durability is doubled against the service
time of conventional battery and provides better performance at
low temperatures.
To install battery unscrew the battery compartment cover (6,
Fig.1). When using CR-123 Lithium type battery, remove the
battery type adapter. Observe the polarity indicated on the
housing. Put the battery in and screw the battery cover back on.
6.2
Switching the unit on
In the daytime put on the lens cap with the daylight filter
prior to switching the unit on.
To check if the unit is operational switch it ON (rotate switch (1,
Fig.1) clockwise) and look through the eyepiece (4, Fig.1). You
should see greenish-lit screen. If the screen is not lit check the
battery.
When the unit is ON user may see either one or two circular
indicators through the eyepiece (Fig. 2). When inactive they are
hardly noticeable. Bright yellow or flashing red spot indicates
low battery voltage. For an uninterrupted operation keep a fresh
11
battery ready and replace it on time. Bright red indicator reminds
the user that the IR illuminator is on (for more details on
illuminator see 6.9).
In the daytime with lens cap on it is
normal to observe a fuzzy image.
Switching on the night vision device
in the daytime is intended for testing
purposes only.
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 allows avoiding
greenish shadow on the face, which
may disclose the user.

left), Low battery indicator
(yellow, right)
6.3
Switching the unit off
After you have finished using the device, turn it off by rotating
switch (1, Fig.1) to OFF position. Put a protective lens cap on the
lens. Remove the battery from the battery compartment to avoid
any damage of the device in case of electrolyte leakage.
6.4
Adjusting to individual vision
Turn on the device. Direct the device at an object placed within
8-15m from the viewer. Obtain the sharpest image possible on
the eyepiece screen by focusing the eyepiece lens (4, Fig. 1) and
then the objective lens (3, Fig. 1).
12
6.5
Focusing
To obtain a sharp image at some other distances adjust the lens
focus (3, Fig. 1) leaving the eyepiece setting intact. You should
be able to obtain a sharp image for distances from 2-10m to
infinity.
If you wear eyeglasses or NBC protective mask, you may like to
fold the rubber eyecup.
6.6
Manual gain adjustment
NVS 14-3GCS monocular is equipped with the manual gain
adjustment handle. The light gain of the Image Intensifier Tube
is set to the level, at which it allows viewing in the darkest
conditions. While outside illumination increases at dusk, dawn,
full moon or in the environment with artificial lights, the tube
enters the Automatic Brightness Control (ABC) mode that
automatically decreases gain to keep the screen brightness on the
same level thus protecting both the tube and the observer’s
vision. It leads to situation when the contrast of the image
(relation between the brightest and darkest patterns on the
screen) becomes lower, and detection/recognition ranges become
shorter. In order to prevent deterioration of device performance
under higher illumination the user can rotate the manual
brightness control knob counter clockwise to restore full
functionality. The brightness control can be adjusted in the range
of 20-100% .

6.7
Auto shut OFF at bright light
The NVS 14-3GCS monocular has a built-in high light sensor
located near the IR illuminator (2, Fig. 1). This sensor shuts the
monocular off after about 45 second 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.
6.8
Using the unit with headgear or helmet
The unit is supplied with headgear (5, Fig. 1). Prior to using the
headgear adjust its straps so that the headgear fits the head
comfortably but firmly and does not slide off when you are
moving.

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 (10, Fig. 1), and then release the knob.
To set comfortable eye-relief (the distance between your eye and
the eyepiece), loosen tightening screw (8, Fig. 1) 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 specially.
To switch between left and right eye, press the flip button (5, Fig.
3) on the mount and rotate it respectively until click.
6.9
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.
15
In “Auto” position of the switch, the monocular will turn off
automatically. Reverse the operation to return the unit to working
position.
6.10
Using IR illuminator
In case of insufficient light when observing a close object turn on
the IR illuminator by turning the switch (1, Fig.1).
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.
6.11
Installation of add-on lenses.
Always make sure that the monocular is switched off when
you put on or take off the add-on lens.
Note: The following procedure is identical for 3x or 5x lenses
FIGURE 4

(or any other add-on lenses).
Turn off the monocular. Remove the lens cap. Press the lens
firmly towards the eyepiece. Do not apply excessive pressure.
Make sure that the lens is fixed well on the monocular. To return
the monocular back to 1x magnification, pull off the lens.
6.12
Demist shield and sacrificial window
Note: Demist Shield and Sacrificial Window are optional.
Sacrificial window protects the objective lens from the abrasive
influence of sand and dust in the night time. It should be put on
the objective lens like an objective cap with the daylight filter.
Demist shield filter protects the eyepiece against fogging. To
install it fold the eyecup to the very bottom to get the full access
to the thread, and screw the filter gently onto the eyepiece.
6.13
Using the camera / video adapter
Before using the (optional) adapters,
remove the rubber eyepiece carefully.
The adapter (Fig. 5) consists of 2 rings:
a) Camera adapter is 52x0.75mm. It
fits the filter lens thread of various
cameras, e.g. Nikon.

Mount binding screw
The unit is fixed to the mount by the locking screw (1,
Fig. 6). To adjust the position of the unit to your eye level
use the screw (4, Fig. 6). To adjust the eye relief first
loosen the locking screw (1, Fig.6) and set a comfortable
distance between the eyes and the eyepiece; then tighten
the locking screw back.
You can fixate the unit in three predetermined positions: vertical,
horizontal, and 15-20 degrees above horizontal. Although the
18
relative angles between these positions cannot be changed, the
starting point can be adjusted by screws (3, Fig.6). If you loosen
them, you can rotate the flip-flop mechanism to find the suitable
starting point. Tighten the screws (3, Fig.6) after the adjustment.
You can raise the unit for unobstructed view without taking the
helmet off. To do so press (and hold) the button (2, Fig.6) and
rotate the unit until you hear a click.
All other operations with the unit mounted on a helmet are
identical to those with the headgear.
6.15
Mounting on a rifle
The unit can be mounted on a rifle with Picatinny mount adapter
(MIL-STD-1913). The optical axle of the monocular coincides
with the rifle’s Picatinny rail.
FIGURE 7. NVS 14-
3GCS with Picatinny
Two types of weapon mount adapters are available – Fig.7 and
Fig. 8. Either adapter enables mounting the unit to the Picatinny
rail. The type shown on Fig. 7 has two screws with large grooved
heads for convenient tightening.
Note: Over tightening the screws may damage the thread.
19
The ‘Quick Release’ model (Fig. 8) utilizes a latch with a spring
and patented accu-torque screw. You can attach and detach your
monocular within a few seconds. The accu-torque screw fixes the
mount with predefined torque thus protecting the thread from
accidental damage caused by over tightening.
The advantages of the ‘Quick Release’ mount are:
.
