1. BRIEF DESCRIPTION  
1.1.  
Overview  
NVS 22-2XT is a night vision attachment to a daytime weapon scope  
designed for precise aiming in darkness.  
The device is equipped with a high-quality electro-optical image  
intensifier tube that amplifies light in the visible and IR spectrum  
providing for up to a 400-700 m effective observation range at low light.  
Observation range depends on the characteristics of the day scope NVS  
22-2XT is attached to and actual observation conditions, such as  
available light, atmosphere transparency and target reflectivity. The  
observation range increases by brighter light, at moon night, or if the  
object is positioned against a light background, such as snow or grass.  
The range decreases at lower light, low atmosphere transparency, or if  
the object is positioned against dark background, such as plough-land,  
desert, stems of trees, etc.

5. OPERATION INSTRUCTIONS  
WARNING!  
Lens cover should be always on when switching on NVS 22-2XT in  
bright light conditions. Never aim the lens in the direction of bright  
light.  
5.1. Battery installation  
NVS 22-2XT requires two AA batteries.  
Prior to installing the batteries make sure  
they are in good condition.  
To install batteries unscrew the battery  
compartment cover 5 (Fig.1), insert  
batteries, observing correct polarity, and  
screw the cover back on.  
NOTE: Alkaline batteries provide longer  
operation time and maximize the power of  
the IR illuminator.

5.2.  
Testing NVS 22-2XT in the daytime  
Daytime mode of NVS 22-2XT was designed for testing purposes  
only. Image may be fuzzy.  
To test the device in the daylight:  
1. Turn switch 7 (Fig.1) into ON position.  
2. Direct the device at an object within 10-20 m from the viewer.  
3. Turning the focus knob 8 (Fig.1) adjust focus to obtain the  
sharpest image visible through the eyepiece.  
NOTE: The device is not supposed to be directed at a bright source of  
light: bright lamps, the sun, welding glare, etc – doing so may result in  
permanent reduction of the light amplification ability of the device. To  
avoid the fatigue of the photocathode do not leave the stationary device  
switched on in the excessively bright environment (dawn, dusk, daylight,  
etc.) for more than 30 minutes.  
5.3.  
Testing NVS 22-2XT at night  
To test NVS 22-2XT in darkness:  
1. Take off the lens cap 6 (Fig.1)  
2. Turn on the device using switch 7 (Fig.1)  
3. By turning knob 8 (Fig.1) and eye-piece 3 (Fig.1) obtain clear  
image of the object.  
5.4.  
Testing NVS 22-2XT at night with day time scope  
1. Install NVS 22-2XT (see Chapter 6 “INSTALLATION ON A  
RIFLE”)  
2. Take off the lens cap 6 (Fig.1).  
3. Turn on the device using on/off switch 7 (Fig.1). Greenish image  
must be seen through the daytime scope.  
4. Select necessary zoom of the daytime scope. By turning knob 8  
(Fig.1) of NVS 22-2XT acquire the target through daytime  
scope.

6. INSTALLATION ON A RIFLE  
1) Loosen slightly the Clamp screw 11 (Fig. 1) of the adapter rail.  
2) Place the NVS-22-2XT onto the Picatinny rail of the fire arm before  
objective of daytime scope at the minimal distance from it.  
3) Tighten the fixing Clamp screws 11 (Fig. 1)  
NOTE:  
- Clamp screws may need to be tightened again after continuous  
shooting.  
- Open the lens cap of the daytime scope prior to installation of  
NVS 22-2XT. With NVS 22-2XT mounted in front of the scope it may  
be impossible to take the scope lens cap off.  
When mounted in front of the daytime riflescope, depending on the  
daytime riflescope and position of night vision attachment to the day  
time riflescope the complete system may change zeroing (bore sighting)  
no more than 1MOA at 100 m.  
This is related to changes in the weapon balance, light distortions in the  
image intensifier tube, technological limits in the adjustment of the  
riflescope attachment. This imprecision usually appears as fixed value  
and can be easily compensated by the adjustment mechanism of the  
7
daytime riflescope. Thus, it is recommended to estimate if adjustment is  
required for a night vision sight in combination with daytime riflescope  
by bore sighting daytime riflescope with and without night vision  
attachment. Value of the required adjustment should be noted in clicks of  
the riflescope and shall be used each time when nigh vision sight is being  
used.  
RECOMMENDATION:  
Please make sure that night vision attachment is mounted on the rifle  
with the following tolerances related to position of daytime scope axis:  
- maximum permissible misalignment of optical axes shall be within ±1  
mm in both vertical and horizontal planes  
- maximum permissible misalignment of optical axes shall with ±1  
degree in both vertical and horizontal planes  
Due to manufacturing process and design of image intensifier tubes, it is  
not always possible to eliminate boresight alignment of 1MOA at 100 m,  
which could appear during shooting. It is recommended to make 10-15  
shots during the scope testing as an additional test before operation in  
real conditions.

7. STORAGE AND MAINTENANCE  
Warning  
If NVS 22-2XT has been kept for a long time at temperature lower than -  
40°C (-40°F), then prior to using the device must be warmed up at an  
ambient temperature of -10°C (14°F) to +40°C (104°F) with relative  
humidity below 80%.  
NVS 22-2XT is a sophisticated precise optical instrument equipped with  
electronics. It should be handled with due care:  
Unit contains fragile components and sensitive optics. Avoid impacts,  
dust, moisture and sharp changes of temperature.  
Do not touch the optical surfaces other than for cleaning. Doing so  
may damage the anti-reflection coating.  
Clean optical surfaces with professional lens cleaning supplies.  
Use only soft clean cloth to clean the exterior of the device.  
Keep away from sources of heat, such as heating appliances, sunlight  
or central heating. Do not keep the device at temperatures higher than  
60oC (140oF).  
Switch off the unit and remove the batteries during the extended  
periods of non-operation.  
Do not apply excessive force or pressure to the lens assembly, this  
may damage fragile elements and thread connections.  
Small dark and/or white marks may be seen in the field of view. This  
does not affect the operational capabilities of the device.  
Do not remove the cover from the lens other than for night-time  
operation.

8. TROUBLESHOOTING  
8.1.  
The scope does not turn on  
Check whether the batteries are installed properly. Check the charge of  
the batteries. Replace if they are weak. Do not mix old batteries with new  
ones.  
8.2.  
The target does not appear in focus.  
Bring the target to the center of the image. By turning the knob 8 (Fig.1)  
achieve the clearest target acquisition on the screen. If NVS 22-2XT is  
used with daytime scope re-focus it. Repeat the focusing of NVS 22-2XT  
and scope if necessary.  
If the image still does not seem to be in focus, clean the lenses. They  
could be foggy or dusty.  
8.3.  
Image has disappeared.  
If the objective lens of switched on NVS 22-2XT are exposed to bright  
light it automatically shuts off to protect the image intensifier tube from  
overload. When it happens, turn the unit off, wait for a few seconds and  
turn it on again.  
If the image has been lost at the moment of a shot, check contacts in the  
battery compartment.  
8.4.  
Condensation accumulates on the parts  
In order to avoid misting of the eyepiece lens at cold use the special  
protective cover.  
8.5.  
Black dots on the screen  
These are some blemishes in the image intensifier, which do not affect  
the performance or reliability of a night vision device. Blemishes may  
vary in size and number; they are inherent in the manufacturing process.  
Most of them are seen in the daytime only and become almost invisible  
during the night time.
