OPERATING

MOUNTING

1. Slightly loosen the horizontal and vertica l
fixing screws on t he 7/8” weaver ra il built
into the scope.
2. Place the scope on the dovetai l mount of
the fire arm making certain that the mount
aligns with the receptor attachment scr ew
groove. Adjust as necessary.
3. Tighten the horizontal fixing screws.
NOTE: Receptor attachment screws may need
to be tightened after continuous shooting.

MOUNTING SYSTEM

The ATN Night Vision Riflescopes Mounting
System allows to change the position of th e
riflescope flexibly on the weapon in relation to
a shooter in combination with the fixed posi-
tions alread y available on th e weaver rail.
For this purpose in the base of the mounting
bracket there is a rail with a fixing projection.
There ar e thre e gro oves in the mountin g
bracket for mo unting this rail. Besid es it is
possible to chang e the position of the rifle-
scope additionall y by 1/3 of inch. For doin g
this one needs to about-face the rail.
To change the positi on of the riflesc ope on
the weaver rail additio nally follow the step s
mentioned below:
1. Unscrew the two screws, which attach
the rail to the mounting bracket.
2. Take the rail out of the groove.
3. About-face the rail in case of necessity.
4. Place the rail into another groove.
5. Fix the rail with the two screws.
NOTE: If the rail is not taken out easily, screw
up tight one of screws into the threaded aper-
ture in the middle of a fixing projection of th e
rail. Continue rotation of the screw. Thus th e
screw will push out a rail from a groove.

BRIGHTNESS ADJUSTMENT

By rotating the “R” handle you may adjus t
the reti cle’s bri ghtness. Adjustment could
be easily seen if you look trought the sc ope
while adjustement.

WINDAGE AND ELEVATION

The vertical and ho rizontal adjustm ents for
the Arie s can be achieved by tur ning th e
elevation and wi ndage adjust ment mecha-
nisms (remove dust cap s first). Each clic k
equals t o 1/8 inches at 100 yar ds. Whe n
reaching the m aximum of rot ation d o not
use force.

FOCUSING

To focus your riflescop e you will need to
adjust the diopter first thing. Simply tur n the
diopter clockw ise until it stops. Th en, while
looking through the diopt er at a subje ct,
slowly turn th e diopter bac k counter cl ock-
wise until the grain in the image is sharp.
NOTE: We suggest that you focus the diopter
during daylight with the filter on.
Next, focus the front lens until the image and
the grain a re both sh arp. When you are in
the low-light conditions and the daylight filter
is off you may focus the front lens to receive
a sharp image, the diopter should not be
adjusted.
NOTE: The front lens should be readjusted as
you view objects at different distances.
