1. BRIEF DESCRIPTION
Precautions
DN-310 is a sophisticated precision optical instrument equipped
with electronics.
Therefore, it should be handled with due care.
DN 310 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
• Nighttime photography and video
•
•
•
•
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).
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 Generation high-quality
electro-optical image intensifier (Gen. II, 25mm 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.).

2. Remove the rubber eyepiece guard from the scope.
3. Set the eyepiece in the medium position.
4. Screw the adapter ring with the camera in an internal groove of
an eyepiece.
2. EXTERNAL APPEARANCE OF THE DEVICE
Objective lens 64mm / F1.2 Objective lens 100mm / F1.5
5. 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 it’s focusing. At
some position of the eyepiece and objective of the camera the
system will be focused exactly.
6. 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 DN 310 only;
7. 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.

3. Set the rifle on the scoped machine.
NEVER OPERATE YOUR NIGHT VISION DEVICE IN
DAYLIGHT AREAS WITHOUT THE LENS COVER ON!
NEVER AIM THE LENS IN THE DIRECTION OF BRIGHT
LIGHT!
4. Direct the rifle to the point of aiming by mechanical sight (bead
with a slot) (if it is 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
DN 310 requires two AA
batteries. Make sure that the
batteries are in good
condition and polarity is
installed as it is indicated on
5. Unscrew the protective caps of the reticule adjustment screws.
Turning those screws obtain the matching of reticule crosshairs
with the aimed point, set by the mechanical sight or LCTS;
6. Remove the rifle from scoped machine and take out LCTS;
7. 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);
the body of battery

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.
-
-
Place the scope on the rail of the rifle in such a position when
your eye coincides with the edge of the Eyepiece Guard or in
case of a large caliber (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;
Place inserts (4,5) in the apertures of the rail (3). The insert (4)
is placed with a projection (B) looking downwards in the
nearest slot on the rail of the rifle. If there is no such a slot, the
insert (4) is placed with a projection (B) looking upwards. It is
recommended to place the inserts at the maximum possible
distance from each other;
b. Testing of operation
During the bright time of the day:
Turn on the on/off switch (13). Lens cap (12) must be on. Direct
the device at an object placed within 10-20 m from the viewer.
Turning the focus ring (10), eye-piece (3) and the brightness
control (9) try to achieve the sharpest image on the screen of the
image tube.
Place clamps (6) and clamp screws (7) in the inserts (4,5). Tighten
screws (6,7) in order to obtain hard fixation. When necessary the
excessive front part of the rail (3) can be removed.
Adaptation has been completed and the device is ready for use as a
hunter’s scope.
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.) for more than 30 minutes.
c. Variant III – side rail for East European (Warsaw Pact) rifles.
Side rail can be used for the installation of DN 310 on a hunting
rifle with side rail.
c. Operation at night
AT MOON LIGHT: Take off the lens cover (12). Turn on the
device-using switch (13). Turning the eyepiece (3) adjust to
achieve the most clear image on the screen. Then obtain the most
clear-cut image of the object focusing with ring (10). Repeat the
steps of focusing if necessary.
The appearance of the device with a side rail is shown below:
AT INSUFFICIENT AMBIENT ILLUMINATION: use the
Infra/Red illuminator (6) activated by rotating switch (8) clockwise.
Select one of three positions of the switch for different power
settings (10, 25 or 75 mW). Furthermore, turn the brightness
control knob (9) for a brighter image.
It is recommended to contact NEWCON OPTIK for installation of
the side rail.
ATTENTION! In case 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.
If brightness of the screen is decreasing, replace the batteries.
Take out the batteries during long periods of non-operation.
Do not forget to switch the device off after end of WORK!

magnification. The lens
(marked as 2x) doubles focal length of the objective. It can be
mounted on a setting thread behind the light filter of the objective
lens (external side of the objective). The 2x magnifier lens must be
tightened to the rest.
(All parts of the alignment are supplied by Newcon Optik).
Installation of the device is performed as follows:
-
Check the elevation of the fastening screws (2), pulling the rail
(3) to the body of the device (1) above the upper surface of the
rail. The height of elevation must not exceed 3.0mm and must
not be less than 2.5mm. It is especially important when the
body of the device has a blind aperture with a thread (front
hole for the device with a 64 mm objective). The elevation
should not exceed 3.5mm for through holes and should not be
less than 2.5mm. This requirement can be met by cutting axle
length of the screws from the side of the thread;
NOTE! In case of simultaneous usage of the IR illuminator
and 2x magnifier lens partial darkening of the image may
occur, as the large 2x lens overlays the light beam from the
IR illuminator. To avoid this the device should be ordered
with Z-like shape I/R illuminator.
Prior to ordering of the 2x magnifier lens for the device with a
weaver mount, it is necessary to check if it is possible to install the
80 mm diameter 2x lens.
-
Prepare the glue (glue is needed, for example, epoxy with the
tear strength not less than 200kg/cm2) according to its
preparation instruction, and put it on the surface (A) of the
plate. The surface of the screws should not have any glue. This
condition is of a considerable importance, since it provides an
opportunity to repair the device and remove the alignment plate
for further adaptation to another rifle;
6. INSTALLING ON A HUNTING RIFLE
Night vision device DN 310 may be used as a nighttime hunting
scope.
Recommendation. The usage of night vision
riflescopes for hunting may be limited or illegal in
your area. Please, check with local authorities prior to
usage.
-
-
-
Apply a hermetic substance (of silicone type) on the thread of
the screws (2);
Fix the rail to the body of the scope with the help of the screws
(2) cut at the required length;
Remove glue surpluses appeared in the place of alignment of
the rail with the body with a dry napkin and let the glue solidify
in accordance to its instruction (for example, 24 hours in case
of epoxy glue);
Device may be used with various mounts that facilitates reliable
fixation of the device to a particular rifle.
For convenient installation the device is supplied without stiff
fixation of the binding to the device, and in most cases that enables
to perform the device installation to a specific rifle model. For
installation you should contact a specialised armourer workshop
(gunsmith) or – if you are qualified enough – perform the
installation yourself.
