WARNING!

Never operate your night vision device at daylight

without the lens cover on! Never direct the

lens to bright light!

The functional device scheme is given on the figure 1 (see
the Exhibit A).

In daylight, the handle (5) is set into the position DAY,
setting the switching mechanism into position (4a). Light
filter (1) must be removed from the objective (2). Visible
image that is formed by the objective (2) is projected onto
the reticle (7) through the collective lens (3) and lens system
(6). It can be viewed through the eyepiece (11) together with
the aiming marks.

If the aiming marks on the reticle (7) are not seen well, turn
the switch SA1 into ON position. The light diode VD1
illuminates the reticle (7). You can adjust the brightness of
the aiming marks by the resistor R1.

6

During night and in dusk turn the handle (5) into position
NIGHT. This sets the switching mechanism into position
(4b), when the image intensifier A2 replaces the lens (3) in
the aiming channel. Internal micro switcher SA2 is
connected mechanically with the handle (5).

Now, when you turn the switch SA1 into ON position, the
power from batteries G1 and G2 is applied to the image
intensifier A2. Visible image from the image intensifier
screen (13) is projected onto the reticle (7) and is viewed
through the eyepiece (11) together with the aiming marks.

In twilight, the light filter (1) should be on the objective (2)
for image intensifier protection from light overloads.

The sight consists of following components: objective (2)
(figure 2) with mounted light filter (1), switching
mechanism (4), eyepiece (14), and interchangeable mount
(17) with fixing mechanism.

The rubber eye shade (16) eases the eye orientation
relatively to sight eye relief, and protects the eye from
recoil. It is fixed on the eyepiece (14) with the clutch (15).

7

Two rechargeable or non-rechargeable batteries of AA type
are organized in a battery pack (5), which is placed into the
battery compartment (6) and closed by cover (7). To fix the
cover (7), turn the latch (8) counter clockwise.

The sight has following controls (see figure 2):

 the ON/OFF switch (10) for turning on the reticle
illumination and image intensifier (SA1 on figure 1);
 the DAY/NIGHT handle (9) for setting the switching
mechanism (4) into the day or night operating mode;
 the hand wheel (3) for smooth brightness adjustment
of the reticle;

 the hand wheel (12) for elevation adjustment;
 the screw (13) for windage adjustment.

8

5. TOOLS AND ACCESSORIES

 Battery control module should be used for the field

inspection of the batteries. It has four LEDs on the front
panel. Numbers “1.1”, “1.2”, “1.3”, “1.4”, which are
marked near the LEDs, indicate battery voltage in
Volts. The accuracy of voltage measurement is 0.1 V.

 The wrench key is designated for turning the windage

screw (13).

 The protected rubber eye shade from the accessories kit

is used instead of the standard eye shade (16). It is
designed for night work under conditions that require
high level of camouflage. It hides the green light spot
on the shooter’s face, when the shooter is not aiming.

 The soft cloth is intended for cleaning of the external

surfaces of optical components, contacts, and battery
control module.

 The bag is intended for packing up the sight and its

protection while carrying and transporting.

 The cover is used when the sight is transported being

mounted on a weapon.

 The accessories are stored inside the cover.

6. GENERAL INFORMATION

6.1 Precautions

NEVER switch the handle day/night into the night position

in a daytime without the light filter on the objective;
NEVER aim the sight to the bright sources of light (flares,
glowing automotive head lamp) when it is on;
NEVER touch the optical components by hands. Dust,
grease and dirt from the optical surfaces must be removed
with the napkin;
NEVER short the circuit between the batteries and metallic
parts of the body;

NEVER use sight not fixed firmly on the weapon;
NEVER press the eye shade too intensively to avoid the

recoil impact;

ALWAYS work with light filter in twilight;
ALWAYS turn off the sight when not in use in night time;
ALWAYS switch the handle day/night into the day position

when the sight is not in use.

10

6.2 General Instructions

Prior to usage, be sure that you understand the sight controls
and fixing mechanism.
If the sight was in storage, clean optical components with
napkin. Remove the lubricant from the metallic surfaces.
In conditions that require high level of camouflage at night
time, set the protected eyeshade on the sight in the following
order:

- unclasp the clutch (15) (figure 2);

- take off the eyeshade (16) together with the clutch (15);

- put the eyeshade (16) into the case;

- take the protected eyeshade from the kit;

- put the clutch (15) on the eyeshade;

- fit the eyeshade to the eyepiece frame, stretching it a

little;

- fasten the clutch.
If the outside temperature is below zero, keep the battery
pack in the inner pocket of your clothes.
Check the voltage of the single battery in the following
order:

- place the power supply into the battery control module,

keeping the polarity right up;

- if any LED is on, the battery is charged, if it is not, then

the battery is discharged and must be replaced.

Install the battery pack on the sight in the following order:

11

- place the ON/OFF switch into the position OFF;
Visibility decreases and / or disappears.
Bright light sources (moon, projectors or headlights) may
result in visibility degradation or even complete
disappearance. If this happens move the scope away from
the light source immediately. The image should be restored
in within 2 minutes.
Poor atmospheric conditions such as fog haze or extremely
dark environments will decrease the visibility distance as
well.

- Place the handle DAY/NIGHT (9) into the position

DAY;

- Open the cover (7) by turning the latch (8) clockwise;

- Take out the battery pack (5);

- Place two charged batteries or two AA cells into the

battery pack (5), observing the marked polarity;

- Locate the groove on the top side of the pack and place

it into the compartment. The battery pack must slide
effortlessly into the compartment;

- Close the cover (7) by turning the latch (8) counter

clockwise.

- Put the light filter (1) on the objective (2). Set the

DAY/NIGHT handle (9) into the position NIGHT, turn
on the ON/OFF switch (10) and put the hand wheel (3)
into the middle position. You should see the aiming
marks on the yellow-green background;

12

- Turn off the switch (10).

In a daytime, set the DAY/NIGHT handle 9 into the
position DAY, check that the switch (10) is in the OFF
position, and then take the light filter (1) off the objective
(2).

In twilight, put the light filter (1) on the objective (2), turn
on the switch (10), and set the DAY/NIGHT handle 9 into
the position NIGHT.

In the night, take the light filter (1) off the objective (2), turn
on the switch (10), and set the DAY/NIGHT handle 9 into
the position NIGHT.

6.3 Mounting on weapon (Side Mount)

Mount the sight on the weapon in the following order:

- Adjust the mounting seat groove (figure 2) with the

mount type “dovetail”;

- Move the sight forward up to the stop and fix it, turning

the handle (23) forward up to the total fixation on the
mount (18). The sight should be screwed tightly to the
mount;

- If the sight is not fixed tightly, take the sight off the

weapon and regulate the clutch on the mount. For this
purpose take off the latch (21) and assure that the
handle (23) is placed on the number of jags that provide
tight fixation of the sight, then place the latch (21) back
on its place.

6.4 Mounting on weapon (Weaver Mount)

Mount the sight on the weapon in the following order:

- Using the allen key, fix tightly the mount on the sight;

- Adjust the sight with the mount on the rail;

- Using the allen key, fix tightly the mount on the

weapon.

7. MAINTENANCE

Keep the sight clean from the dust and dirt while operating.
Surfaces of the optical components should be always clean.
Clean the glass surfaces with flannel or cotton wool
saturated with ethanol or special cleaning solvent to remove
grease.

- Wind a bit of a cotton wool at the end of wooden

spatula;

- Wet cotton with the solvent;

- Wipe the glass by wetted cotton, not touching the

frame;

- Change the wool to a dry piece and finish cleaning by

circular motions from center to edge.

While cleaning, be careful to not afford the solvent to
penetrate under the frame. This will lead to the dissolution
of the jointing putty and breaking of the sight sealing.

To remove dirt from the battery pack contact plates, battery
pack and from the contacts of the control module YK­battery use the similar procedure.

It is necessary to keep maintenance of the sight to provide
constant readiness and reliability, increase durability, and
remove the signs of untimely wear and tear and damage of
the component units and parts.

9. STORAGE

When preparing the unit for long-term storage, it is
necessary to perform corrosion proofing with a special
lubricant. Each 4 (four) years the lubricant should be
renewed to fully protect the device from corrosion. During
this operation the rest of previous lubricant coating should
be removed, and all metal surfaces should be degreased by a
cotton-wool cloth moistened in benzene. The new lubricant
coating should be applied after degreasing with a brush. The
plastic surfaces don’t require anti-corrosion coating.

When preparing for long-term storage the NVS 10MGs
received from the manufacturer or from the workshops, it is
necessary to check the completeness of equipment by
comparing what is available with the list of components in
the this document. The reliability of NVS 10 MG
attachments to weapon and parameters of adjustment by
azimuth and elevation should be checked with NVS 10MG
mounted on the weapon

When stored, the cases with NVS 10MGs should be placed
on stands, shelves or in cupboards at a dry, heated and
ventilated premise. The temperature at the premise shall be
between +5C and +35C, relative humidity — not more than
55% at temperature +25C.

17

It’s allowed to store the units in transportation case at
temperatures up to 70C (158 F) for not more than 10 hours.
It is unacceptable to place the NVS 10MGs on the floor,
near stoves and windows that let through direct sunrays.
Presence of acid and alkaline vapour, as well as of other
aggressive admixtures in the air is unacceptable.

After a 4-year period of storage, it is necessary to perform
thorough check-up of the NVS 10MGs’ functionality.
