1. BRIEF DESCRIPTION
1.1 Overview
DN 482/483 Night Vision Scope (the unit) is a modern versatile night vision device
designed for a wide range of amateur and professional activities:
Night time observation and hunting
Law enforcement and security
Search and rescue
Wildlife observation
Night time photography and video
The device is equipped with a high-quality electro-optical image intensifier (Gen. 2+/3,
18 mm, MCP) that that amplifies the image brightness in the visible and IR spectra,
thus providing for up to 400 – 700 m observation range in low light conditions.
The unit has two modifications: 3.7x and 6.1x; the first one is pictured in this
document.
The observation range depends on the characteristics of the day scope the unit is
attached to and actual observation conditions, such as available light, atmosphere
transparency and target reflectivity. The observation range is increased by brighter
light, at the 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 the dark background, such as a plough-land, desert,
stems of trees, etc.
1.2 Key Features

5. OPERATION INSTRUCTIONS
5.1 Battery installation
Unit 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), insert batteries observing polarity, and
screw the cover back on.
NOTE: Alkaline batteries provide longer operation
time and maximize the IR illuminator power.
5.2 Testing the unit by daylight
Never operate your night vision device by daylight without the lens cover on!
Never aim the lens in the direction of bright light!
To test device in the daylight:
1. Turn switch (9, Fig.1) into ON position.
2. Direct the device at an object within 10-20 m from the viewer.
3. Turning the focus knob (10, Fig.1) and eye-piece (3, Fig.1) adjust focus to
obtain the sharpest image visible through the eyepiece.
Note: Daytime mode of the unit operation (with lens cap on) was designed for testing
purposes only. Image may be fuzzy.
The device is not supposed to be directed at a bright source of light: bright lamps, the
sun, welding, etc – doing so may result in permanent reduction of the light
amplification capability of the device. Also, to avoid the fatigue of the photocathode it
is not allowed to leave switched on device motionless in the excessively bright
environment (dawn, dusk, daylight, etc.) for more than 30 minutes.
Figure 2.
5.3 Switching the unit off
After you have finished using the unit, turn it off by rotating switch (9, Fig.1) to OFF
position. Ensure the protective lens cap is on the lens. Remove batteries from the
battery compartment to avoid damaging the device in case of electrolyte leakage.
5.4 Operating the unit at night
To operate in darkness:
1. Take off the lens cap (6).
2. Turn on the device using switch (9).
3. Turning knob (10) to obtain clear image of the object.
If ambient illumination is insufficient, activate the infrared illuminator 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.

Page 10
6. UNIT ADJUSTMENT ON THE RIFLE
The adjustment of the scope should be performed either in the daytime with the lens
cap on or in the twilight using an adjusted target or a remote point.
6.1 Reticle
Unit has a reticle shown on Figure 3.
The distances between dots are given in meters at 100
m range. For ranges other than 100m the distances must
be calculated proportionally.
Brightness of the reticle may be adjusted by the knob
(8, Fig.1).
6.2 Adjustment procedure
Attach the unit to the rifle. Prior to adjusting the
scope its objective should be focused on the target.
Set up a panel with a target at 100 m.
Set the rifle on the gun rest to eliminate human error as much as possible.
Making certain the rifle is empty with no cartridge in the chamber and the breech is
open, install the mechanical or laser bore sighter. Install laser bore sighter in the
muzzle of your rifle lining it up with the scope as close as possible.
Looking through the scope as though you were going to shoot you should see
reticle produced by the unit and a cross hair produced by the bore sighter. They
should line up with each other vertically, horizontally and be in complete
alignment. If they are not parallel to each other, adjust the bore sighter in the
chamber.
Unscrew the protective caps of the reticle adjustment screws. Turning those screws
match reticle crosshairs with the aimed point, provided by the mechanical sight or
laser bore sighter.
Remove the bore sighter from the muzzle. Make 2-3 shots. Having examined the
target, make necessary corrections. For example, in order to move the hit point
downwards and leftwards, adjustment screw should be turned counter-clockwise,
in the Down and Left directions. The aiming point will move upwards and
rightwards correspondingly.
If you do not hit the paper target at all, move the target closer until you consistently
hit somewhere on the target. You cannot make any scope adjustments if you do not
know which direction to make it. Do not be concerned if you did not hit the bull’s
eye. Once you initially hit the target sheet you can make adjustments and then
gradually move the target back out to the 100 yard mark.
When the desired precision is achieved set the protective caps into their places.
The unit is now ready for operation.

7. TAKING PHOTOS AND VIDEO SHOOTING
Unit can be supplied with an optional adapter for photo/video cameras for night
photo/video shooting.
Night photo shooting can be performed by 35mm SLR cameras, with standard objective
lens (50-58 mm focus), such as Nikon, Canon, Pentax.
7.1 Attaching Unit to photo/video camera
Screw the supplied adapter ring (52 mm or 37 mm diameter) in the objective lens
of your camera.

Figure 4.
6
If the objective lens of your camera has another diameter for a light filter (for
example, 49mm or 58mm) use step-up or step-down adapter rings from the 52 mm
to your size. Such adapters are not supplied by Newcon; they are generally
available through camera stores.
Remove the eye cup (4, Fig.4) from the unit.
Set the eyepiece (1, Fig.4) in the middle position.
Screw the adapter ring (5, Fig.4) attached to camera into internal eyepiece thread.
Switch on the device and focus the assembled system with the help of the
objectives of the device and the camera.
If image cannot be focused detach the camera and turn the coupling of Unit’s
eyepiece a little. Assemble the system again and attempt focusing. At some
position of the eyepiece and objective of the camera the system will be focused.
Fasten the adapter ring with the camera to the body of the eyepiece of the unit with
three locking screws.
Turn Unit’s objective to focus the system while shooting.
Set diaphragm of the camera to 2.8 or 4 (shooting is possible at lower diaphragm
too, but the images will have lower quality). Taking photos with a fully opened
diaphragm is justified only when shooting quickly moving objects.
7.2 Diaphragm and shutter speed
The TTL system, installed at most SLR cameras, will properly estimate exposure while
shooting with the unit. If your camera is not equipped with the TTL system, the table
8
Page 12
below will help approximately estimate the shutter speed at the diaphragm of 2.0 for
your film:
Film sensitivity (ISO) 50 100 200 400 800 1600 3200
Shutter speed, sec. 1 1/2 1/4 1/8 1/15 1/30 1/60
Use ISO 400 film or higher. Usage of a tripod is strongly recommended to obtain
higher quality photos.
8. STORAGE AND MAINTENANCE
If Unit has been kept for a long time at temperatures lower than -40°C (-40°F), then
prior to its using it must be warmed up at an ambient temperature of -10°C (14°F) to
+40°C (104°F) with relative humidity below 80%.
9. TROUBLESHOOTING
9.1 The scope does turn on
Check that the batteries are installed properly. Check the charge of the batteries.
Replace if they are weak. Do not mix old batteries with new ones.
9.2 The target does not appear in focus.
Bring the target to the center of the image. By turning the knob (8, Fig.1) achieves the
clearest target acquisition on the screen. If used with daytime scope re-focus it. Repeat
the focusing of DN 482/483 and scope if necessary.
If the image still does not seem to be in focus, clean the lenses. They could be foggy or
dusty.
9.3 Image has disappeared.
If the objective lens of switched on DN 482/483 is 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.
9.4 Condensation accumulates on the parts
In order to avoid misting of the eyepiece lens in the cold use special protective cover.
9.5 Black dots on the screen
These are the 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; those are
inherent in the manufacturing process. Most of them are seen in the daytime only and
become almost invisible during the night time.
9
Page 13
9.6 Bright spots on the screen
The image may contain some bright spots caused by gradual relief of static electricity
from the cathode. This feature may appear immediately after the assembling of the
device or attaching/detaching of the objective lens, and it always disappears within 5-14
days of usage or storage.
