1. BRIEF DESCRIPTION
Overview
DN 532/DN 533 device (the unit) is a universal
riflescope, intended for shooting and around the clock
observation. The unit has two eyepieces – for day and
night observation. The night vision eye piece has an
integrated IR illuminator.
Powerful high light ratio optics of the daytime part
provides 7x or 11x magnification. The night-time
eyepiece contains an image
intensifier tube, which amplifies light in visible and near
infrared spectrum.
Unit provides night recognition range of 400-800 m,
system magnification 3.7x or 6x times and visual angle
7.4 (7x) or 4.6 (11x) degrees.

Key Features
All known models of day/night scopes with removable
eyepieces use standard optic scheme of a day-vision scope
with 11-13 lenses. As a rule, the actual F-number of all
system does not exceed 3.0 (sometimes 2.0), which is not
enough for the night vision equipment. Also, as common
day time scopes have relatively small field of view, in a
night mode only small central part of the electronic tube
working area is used. A unique 23 lens design provides
the unit a 2-2.5 stronger light transmission (F 1.5 with 66
mm aperture), twice wider field of view and entire
working area of the photocathode.
High resolution 18 mm Image Intensifier Tube and
special light-collecting optics provide bright, sharp
image of consistent quality from the center to the
edges.
Powerful IR illuminator (optional) is effective for up
to 200 m
Unit is equipped with automatic brightness protection
Camera/video adaptable
Precise internal windage/elevation adjustments
Standard weaver mount or optional weaver rail or
side rail mounts
Long eye relief
The scope is water resistant and can be used in rain.

Using the Night Vision Eyepiece as monocular
As standard the NV monocular gives an inverted (upside-
down) image.
To provide a ‘normal’, non-inverted image, you need to
attach an optical inverter
to the back of the NV’s existing eyepiece (4). This is done
by screwing it in clockwise.
Warning ! Do not overtighten or misalign the inverter.
The NV Eyepiece is now ready for use as a night vision
monocular.
To increase the magnification of the NV Eyepiece
(standard magnification 1x),
you can use the optional 3x magnifier lens which provides
3x image magnification.
The 3x magnifier lens can be fitted in two ways:
- Install the magnifier 3x with the supplied adapter ring
(2).
Screw the adaptor ring on to the rear of the magnifier
lens. Push the lens/adaptor ring over the front of the NV’s
lens. This allows a quick push on/pull off magnification
capability, but is not designed for long term observation.
- Leave the adaptor ring (2) off and screw the magnifier
lens directly in to the screw
thread inside the front of the NV’s objective lens. This is
a more secure assembly designed for long term
observation.

OPERATION
Changing eyepieces
Do not apply superfluous force while changing eyepieces!
To change day time eyepiece for a night time one and the
other way around:
1. Holding the unit firmly in two hands push the
bayonet button towards objective (as indicated by
arrow on the Fig. 5) and turn the eyepiece counter
clockwise till stop.
2. Pull the eyepiece away from the scope body. Slight
effort may be required to overcome air depression
resulting from opening a water-resistant connection.
Pack the eyepiece safely.

Unit and eyepiece together and turn eyepiece
clockwise till you hear a slight click.
Using the scope in the daytime
With daytime eyepiece attached take the objective cover
off. Rotate the eyepiece to get the reticle in focus. To
eliminate parallax of the objective lens set the
approximate observation range (observation range in
metres is indicated) using the focus adjustment knob (6,
Fig.4).

Fig 7. Installing
battery into night time
eyepiece
Using the scope in the nighttime
For night time use attach the night vision eyepiece as
described above. This eyepiece requires a battery to
operate.
Battery installation
Night channel of the unit utilizes one CR123A Lithium
battery. Prior to installation make sure that battery is in
good condition. Install the battery into the battery
compartment of the night time eyepiece observing the
polarity, as indicated on the body and inside the battery
compartment. An optional IR illuminator utilizes 2 AA
batteries. Follow the similar procedure

15
Night time operation
Take off the objective lens cap.
Switch the unit on by turning the switch into position ON.
In a few seconds greenish fluorescent glow will become
visible through the eyepiece.
Rotate the eyepiece focus adjustment ring until you get
the reticle in focus.
Turn the distance adjustment knob until you get the best
image.
If you need to illuminate the observed object, install and
switch on the optional infrared illuminator.
Warning!
Do not use night-time eyepiece in the daytime.
Do not aim the working night-time eyepiece toward sources of
bright light: lamps, welding, etc. – that may cause decrease of
the light amplification coefficient.
Do not leave the switched on night time eyepiece motionless for
more than 30 minutes in semi-bright conditions to avoid
photocathode fatigue.
Switching the unit off
After you have finished using the unit, turn it off by
rotating switch to OFF position. Ensure the protective
lens cap is on the lens. Remove batteries from the battery
compartment to avoid damage of the device in case of
electrolyte leakage.

5. INSTALLATION ON A RIFLE
The unit may be used as a day time or a night time
riflescope. The unit may be supplied with various mounts,
such as:
Standard prism – SP 532
Weaver 7/8’’ rail – WP 532 (default
configuration)
Side mount or side mount adapter.
The particular mount configuration is determined by the
order.
The unit may be supplied without a binding attached to it
to enable installation on a specific rifle model. Contact a
gunsmith for installation.
Adjustment procedure
Scope adjustment is necessary for either day or night time
configuration. Exchange of the eyepieces does not affect
it.
Attach the unit to the rifle.
Set up a panel with a target at 100 m. Focus scope on
the target.
Set the rifle on the gun rest to eliminate as much
human error as possible.

17
Making certain the rifle is empty with no cartridge in
the chamber and the breech is open install
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
with 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 are not hitting the paper target at all, move the
target closer until you consistently hit somewhere on
the target. You cannot make any scope adjustments if
