1. BRIEF DESCRIPTION
DN482/483 Night Vision Scope is a modern, universal night vision
device designed for a wide range of activities from amateur to
professional needs:
• Nighttime observation and hunting
• Law enforcement and security
• Search and rescue
• Wildlife observation
Precautions
DN482/483 is a sophisticated precision optical instrument equipped
with electronics.
Therefore, it should be handled with due care.
•
•
•
•
Keep your device away from direct sunlight, impacts, dust,
moisture, and sudden changes of temperatures.
Do not keep the device at temperatures higher than 60oC
(140oF).
• Nighttime photography and video
Do not touch the optical surfaces with fingers. Doing so may
damage the anti-reflection coating.
Cleaning of optical surfaces is only allowed with professional
camera lens cleaning supplies.
The device is equipped with a Second or Third Generation high-
quality electro-optical image intensifier (Gen. II+/III, 18 mm MCP)
utilizing the principle of multiple intensification of the image
brightness in the visible and IR spectrum which guarantees an up to
400 – 700 m observation range.
•
•
•
•
To clean the exterior of the device, use a soft clean cloth.
Do not take the cover off the lens if not necessary.
Keep away from heating appliances and central heating.
Make sure to switch off the unit during periods of non-
operation and when storing the device for long period of time.
Do not apply superfluous efforts at work with lens assembly,
agile elements and thread connections.
Due to considerable optical magnification of the eyepiece some
small structures inside the tube coating in the form of dark
and/or white points may be seen in the field of view, which
does not affect the serviceability of the device.
NOTE.
Detection and recognition range provided by the device depends on
the type of the objective lens used and the observation conditions:
light available, transparency of the atmosphere and target quality.
The identification range increases in the conditions of high light, at
moon night, if the target is situated on a light background (sand,
snow). The identification range decreases in the conditions of low
light, low transparency of the atmosphere, if the target is situated
on a dark background (plough-land, stems of trees, etc.).

• Switch on the device and focus the assembled system with the
help of the objectives of the device and camera. If the image
cannot be focused the camera with the ring should be removed
and the coupling of the eyepiece of the device should be rotated a
little. Assemble the system again and check its focusing. At some
position of the eyepiece and objective of the camera the system
will be focused exactly.
• Fasten the adapter ring with the camera to the body of the
eyepiece of the device with the help of three locking screws.
During further photo shooting sharpness of the system is obtained
with the help of the objective of the DN482/483 only;
• Set diaphragm on the objective of the camera equal 2.8 or 4
(shooting is possible even at lower diaphragm settings, for
example 2, but the obtained pictures will have worse resolution).
Taking photos with a completely opened diaphragm of the
objective is justified for the shooting of quickly moving objects
only.

the objective.
The adjustment of the scope should be performed either in daytime
with the closed cover of the objective or in the twilight using an
adjusted target or a remote point.
5. OPERATION INSTRUCTIONS
WARNING!
Adjustment of the scope is performed in the following way:
NEVER OPERATE YOUR NIGHT VISION DEVICE IN
DAYLIGHT AREAS WITHOUT THE LENS COVER ON!
NEVER AIM THE LENS IN THE DIRECTION OF BRIGHT
LIGHT!
• Fix the scope on the rifle.
• Set a panel with a target or select the point of aiming.
• Set the rifle on the scope machine.
• Direct the rifle to the point of aiming by mechanical sight (bead
with a slot) (if possible). At this stage it is suitable to apply laser
of cold test shooting (LCTS) inserted in the barrel of the rifle,
which indicates geometrical point of the barrel position (sold
separately).
a. Battery installation
DN482/483 requires two AA batteries. Make sure that the batteries
are in good condition and polarity is
installed as it is indicated on the body
of battery compartment (5).
• Unscrew the protective caps of the reticle adjustment screws.
Turning those screws obtain the matching of reticle crosshairs
with the aimed point, set by the mechanical sight or LCTS;
• Remove the rifle from scoped machine and take out LCTS;
• Make 2-3 shots. Having examined the target make necessary
corrections (for example, in order to move the hit point
downwards and leftwards, screws of the mechanism should be
turned counter clockwise, in the directions Down and Left
correspondingly. The aiming point is moving upwards and
rightwards correspondingly);
In order to change the batteries
unscrew the cover of battery
compartment (5) and install the new
batteries, observing correct polarity.
NOTE: In order to ensure the longest operation time of the device
and full power of the IR illuminator (using one set of batteries) it is

recommended to use Alkaline batteries, which ensure the most
stable performance.
(for example, .375 H&H Mag) your eye should be situated at the
distance of 2-5cm from the edge of the Eyepiece Guard. The device
should be located in the position which allows comfortable
observation without stretching forward;
b. Testing of operation in a daytime
• Place inserts (4, 5) in the apertures of the rail (2). The insert (4) is
placed with a pimple looking downwards in the nearest front slot
of the rifle rail. If there is no such a slot, it’s recommended to
make it at a gunsmith workshop.. It is recommended to place the
inserts at the maximum possible distance from each other;
• Place clamps (6) and clamp screws (7) in the inserts (4, 5).
Tighten screws (7) in order to obtain hard fixation. When
necessary the excessive front part of the rail (3) can be removed.
Installation is completed and the device is ready for use as a
hunting scope.
During the bright time of the day:
Turn on the on/off switch (9). The lens cap (6) must be on. Direct
the device at an object placed within 10-20 m from the viewer.
Turn the focus knob (10) and eye-piece (3) try to achieve the
sharpest image on the screen of the image tube.
NOTE: The device won’t burn out even if it is exposed to a bright
light. The automatic shut-off system will make the screen dark.
After replacing the device into dark environment the tube will
recover in few seconds.
CAUTION!
The device is not supposed to be directed at a bright source of light:
bright lamps, the sun, welding and etc – it may result in the
reduction of the light gain of the device. In order to avoid the
fatigue of photo-cathode it is not allowed to leave the active device
motionless in the excessively bright environment (dawn, dusk,
daylight, etc.) during more than 30 minutes.
c. Variant III – side rail for East European (Warsaw Pact) rifles.
Side rail can be used for the installation of DN482/483 on a hunting
rifle with side rail. The appearance of the device with a side rail is
shown below:
c. Operation at night
AT MOON LIGHT: Take off the lens cover (6). Turn on the
device-using switch (9). Turn the eyepiece (3) adjust to achieve the
best shape of the reticle. The reticle brightness can be adjusted by
switch (8). Then obtain the most clear-cut image of the object
focusing with knob (10). Repeat the steps of focusing if necessary.
AT INSUFFICIENT AMBIENT ILLUMINATION: use the
Infra/Red illuminator activated by rotating switch (9). Select one of
three positions of the switch for different IR power settings (10, 25
or 75 mW). If brightness of the screen is decreasing, replace the
batteries.
It is recommended to contact NEWCON OPTIK for installation of
the side rail.
ATTENTION! In case if you use other type of binding, to
eliminate the phenomenon of shooting point displacement, device
binding should be advised with Newcon Optik, because usually
such displacement is caused by unqualified installation.
It’s recommended to take out the batteries during long periods of
non-operation.
Do not forget to switch the device off after end of work!
