Your Dedal-450 Night Vision Scope is a modern, universal night vision device designed
for a wide range of activities from professional to amateur activity:
- Night observation and hunting,
- Patrolling and safeguarding,
- Rescuing and searching works,
- Law/police enforcement.
The device is equipped with high quality image intensifier tube Gen. II+, III employing
the principle of multiple intensification of the image brightness in the visible and IR
radiation which guarantees great observation range.
Note.
Observation and identification range provided by the device depends on the value
natural night light, type of the objective used, transparency of the atmosphere and
contrast between the target and background. The identification range increases in the
conditions of good lightning, at moony night given outside illumination if the target is
situated on the light background (sand, snow). The identification range decreases in
the conditions of weak lightning, low transparency of the atmosphere if the target is
situated on the dark background (plough-land, stems of trees, etc.).

Installation of batteries

7
Your device Dedal-450 works from two batteries of AA
type. Be sure that the batteries are in good condition and they
are installed in accordance to the picture on the battery
compartment.
In order to replace batteries it is necessary to turn off a cover
of the battery compartment and replace old batteries with
new ones, keeping polarity of the batteries.
Note.
The light intensity of the center of the reticle could be used as low battery
indicator. With IR illuminator switched on with full power and during reduction of
the electric potential under 1.9 V the brightness of the reticle decrease as
compared to the normal rate. If the electric potential continue to decrease the
reticle stop shine and the batteries must be changed to a new ones.
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 batteries of
Alkaline system, possessing the most stable characteristics of a current
consumption when their power capacity is reduced.
Function test in a daytime
In order to test operation of the device you can turn it on with the closed objective cover
in a daytime. Objective cover of has a small hole enough to test the operating condition
of the device. When the device is turned on the observed picture appears on the screen in
a yellow-green color.
Note.
The device won’t burn out even if you open the cover of the objective. When the
light is excessively bright protection will be activated (automatic adjustment of
brightness) and the image will curtail. When the device is placed into a dark place
the image will be restored in several seconds.
Caution.
The device is not supposed to be directed to the bright sources of light: bright
lamps, the sun, welding and etc – it may result in the reduction of the coefficient of
brightness magnification of the device. In order to avoid the fatigue of photo-
cathode it is not allowed to leave the device motionless in a turned on condition in
the excessively bright environment (in the morning, in the evening, in a daytime)
for more than 30 minutes.
Use of the device in a dark time

8
1. Take off (оpen) the cover of the objective.
2. Turn on the device - position ON of the switch (8). Green light should appear on the
screen (the device works in a passive mode).
3. Turning the eyepiece (3), reach the sharpest image of the reticle. The brightness of the
reticle can be adjusted by the switch (9).
4. Choose the object of observation and focus the objective of the device with the handle
(10) till the receipt of maximally clear, distinct and sharp image of the observed object.
5. When illumination of the observed object is required, turn on (8) IR illuminator (active
mode). You can select one of the three positions changing the illuminator’s power (10, 25
or 75 mW). The direction of glow of IR illuminator could be adjusted by moving body of
the illuminator in vertical direction. In addition, with the help of rolling IR lens, the glow
could be adjusted in full-circle, which allows to move IR plash directly to the centre of
the screen.
6. Having finished the work, turn the ON / OFF switch (8) to the position OFF.
7. Close the cover of the objective after you have finished the work the device.
Recommendation.
When the device is stored for a long time it is recommended not to leave batteries in
the compartment of the device in order to avoid leakage of the batteries.
Do not forget to turn off the device after use!
Adaptation to a hunter’s rifle
Your night vision device Dedal-450 can be used as hunter’s night vision riflescope.
Recommendation.
We recommend you to specify the order of usage of the hunter’s scope on your rifle
with the local competent authorities.
Your night vision device Dedal-450 can be used with different types of mounts,
providing reliable fixation of the device on the particular rifles. Manufacturers of civil
rifles do not possess uniform standards for a mounting place of optical devices, and as a
result universal fastening device is not available. The device Dedal-450 is supplied with a
fastening mount without hard fastening to the body, in most cases allowing the
performance of special adaptation of the device for a particular model of rifles. For this
purpose you should address to a specialized rifle workshop or implement the fastening
yourself, if you possess enough qualification, following “The rules of adaptation of
“Dedal” night vision riflescopes”.

Caution.
In case of using another variant of adaptation or alternative type of mount, please
coordinate it with JSC Dedal-NV. Most cases of uncontrolled displacement of
mean point of impact are concerned with incorrect adaptation.
Type and dimensions of the reticle
The reticle is Mil-Dot type.
The central part of the reticle is shown at the picture. The
brightness of the central point of the reticle can be adjusted with
the toggle switch (9). The magnitude of displacement of the

10
reticle by turning for one click at the distance 100m is 15mm (½ MOA). The dimensions
are indicated in meters at 100m distance.
Adjustment of the scope on the rifle
Before the adjustment of the scope its objective should be adjusted for a distant object
(select infinity) in a dark time with the opened cover of the objective.
Adjustment of the scope can be performed in a daytime with the closed cover of the
objective or in the twilight on the adjusted target or on the remote point.
Adjustment of the scope is performed in the following way:
– fix the scope on the fit of the rifle;
– set a panel with a target or select the point of aiming;
– set the rifle on the scoped machine;
– 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 inserted in the
barrel of the rifle, which indicates geometrical point of the
barrel position. Such lasers are supplied by the JSC Dedal-
NV;
– unscrew the protective caps of the bias screws of the aimed graticule. Turning the
bias screws of the reticle obtain the matching of reticle crosshairs with the aimed point,
set by the mechanical sight or cold test shooting
– remove the rifle from scoped machine and take out cold test shooting;
– 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 clockwise, in the directions Down and Left
correspondingly. The aiming point is moving upwards and rightwards);
– make a control shot and find out whether the aiming point coincides with the bullet
hit point. (Make the correction again if necessary);
– the shoot in position of windage/elevation mechanism could be set in a zero
position. For that end you should unscrew three screws of the knob with allen key (not
included in the standard set) and turn the knob until the zero position of the knob
coincide with special mark on the body of the scope. Use the same key to fix the
elevation knob with three screws.
– fix the protective caps
– the device is ready for operation;
Note.
In view of speciality of manufacturing technique and design of vacuum technique, it
is not always possible to eliminate all hidden defects, which could appear during
impulse load when shooting. It is recommended to make 10-15 shots during
adjustment fire to make additional control before real operation.

Protect the box from moisture penetration and the device should be protected from direct
sun influence. The device should be kept in a warm, dry place far from heating devices,
batteries should be taken out. Storage temperature must not exceed 60°C.
Troubleshooting
The device Dedal-450 does not work...
Make sure that the batteries have been installed and they are in good condition.
Dedal-450 can not be focused...
Adjust the objective lens and eyepiece according to the instructions specified in the
Operation section. If the device is not still focusing wipe and clean the optical parts.
The image has faded or disappeared completely…
Bright source of light can be a reason of the image reduction, loss of resolution or
complete disappearance. This is an automatic protection system of the device. If Dedal-
450 has been switched off automatically, turn the switch to the position OFF. The unit
will be ready for use in one-two seconds.
Condensation effect…
In order to avoid misting of the eyepiece lens in cold time use special anti-damping
covers (for example, for a spectacles).
Some black dots are on the screen…
The image may contain small black dots or groups of black dots. Most of black dots can
be seen only in daytime and in the operation mode the dots become almost invisible.
Bright points are on the screen…
The image may contain some bright points caused by gradual relief of static electricity
from the cathode. This feature may appear immediately after the assembly of the device
and removal/setting of the objective from/to the device, and it always disappears in 5-14
days of the device utilization (storage).
