5. OPERATION INSTRUCTIONS  
5.1  
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.  
5.2  
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)) and look through the eyepiece (3, 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  
battery ready and replace it on time. Bright red indicator reminds  
8
 
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 goggles 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.

(yellow, right)  
5.3  
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.  
5.4  
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 and then the  
objective lens (2, Fig. 1).  
9
 
5.5  
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.  
5.6  
Manual gain adjustment  
NVS 15 goggles 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% .  
10  
 
5.7  
Auto shut OFF at bright light  
The NVS 15 goggles has a built-in high light sensor located near  
the IR illuminator (2, Fig. 1). This sensor shuts the goggles off  
after about 45 second exposure to light exceeding 10-1 lux.  
To reset the goggles 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.  
5.8  
Using the unit with headgear or helmet  
The unit is supplied with headgear. 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 using standard  
headgear/helmet mount already  
attached to the NVS bridge (5, Fig. 1).  
1
To attach headgear to loosen the  
tightening screw (2, Fig. 3) on  
headgear, slide the standard mount on  
the bridge onto the rail on the  
headgear/helmet mount, and then  
tighten the screw.

FIGURE 3  
To set comfortable eye-relief (the distance between your eye and  
the eyepiece), loosen tightening screw (8, Fig. 3) on the headgear  
and move the unit, then tighten the locking screw.  
11  
 
5.9  
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 (1, Fig.  
3) and raise the device until you hear a click.  
In “Auto” position of the switch, the goggles will turn off  
automatically. Reverse the operation to return the unit to working  
position.  
5.10  
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.  
12  
 
5.11  
Installation of add-on lenses.  
Always make sure that the goggles is switched off when you  
put on or take off the add-on lens.  
FIGURE 4  
NVS 15 Single unit with  
attached 3x lens  
Note: The following procedure is identical for 3x or 5x lenses  
(or any other add-on lenses).  
Turn off the goggles. 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 goggles. To return the  
goggles back to 1x magnification, pull off the lens.  
5.12  
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.  
13  
 
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.  
5.13  
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.  
5.14  
Using the helmet mount  
The unit can be equipped with an optional helmet mount.  
This mount can be customized to fit a wide range of  
existing helmet models.  
The mount is attached to a helmet with straps.

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  
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.  
15  
 
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.  
5.15  
Mounting on a rifle  
The unit can be mounted on a rifle with Picatinny mount adapter  
(MIL-STD-1913). The optical axle of the goggles coincides with  
the rifle’s Picatinny rail.  
FIGURE 7. NVS Unit  
with Picatinny adapter.  
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.  
The ‘Quick Release’ model (Fig. 8) utilizes a latch with a spring  
and patented accu-torque screw. You can attach and detach your  
goggles 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.

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  
daytime scope with the help of an optional  
NVS Coupler.

5.17  
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 goggles to the bridge. In  
this configuration the unit can be  
used in a goggle (mounted on a  
headgear) or handheld.
