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.

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 (8, Fig. 1) 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 (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  
NVS 14-3GCS with attached 3x  
 
(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.  
FIGURE 5  
b) Video adapter is 37x0.75mm. It  
fits Sony cameras and some others.  
Camera / Video adapter  
If our adapter does not fit your camera obtain a proper step up /  
step down rings.

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:  
.
.
Quick removal and installation of the device;  
Foolproof design;

Increased reliability.  
6.16  
Using with a daytime riflescope  
Although the unit does not contain a reticle  
and thus cannot be used as a riflescope,  
being mounted on a daytime riflescope or  
red-dot sight, it enables aiming at night.  
In this configuration the objective lens of  
the unit is mounted on an eyepiece of the  
FIGURE 9.

daytime scope with the help of an optional NVS Coupler.  
6.17 Binocular configuration  
Two units can be combined into dual channel goggles/binoculars  
with the help of an optional bridge. Optional lens can be attached  
to form a binocular 3x system.  
To form a double-unit system use the  
dovetail platform (10, Fig.1) located on  
both sides of the unit. These platforms  
are identical.  
The tightening screw (8, Fig. 1) locks  
monocular to the bridge. In this  
configuration the unit can be used in a  
goggle (mounted on a headgear) or  
handheld.
