OPERATING
MOUNTING
1. Slightly loosen the horizontal and vertical
fixing screws on the 7/8” weaver rail built
into the scope.
2. Place the scope on the dovetail mount of
the fire arm making certain that the mount
aligns with the receptor attachment screw
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 the
riflescope flexibly on the weapon in relation to
a shooter in combination with the fixed posi-
tions already available on the weaver rail.
For this purpose in the base of the mounting
bracket there is a rail with a fixing projection.
There are three grooves in the mounting
bracket for mounting this rail. Besides it is
possible to change the position of the rifle-
scope additionally by 1/3 of inch. For doing
this one needs to about-face the rail.
To change the position of the riflescope on
the weaver rail additionally follow the steps
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 the
rail. Continue rotation of the screw. Thus the
screw will push out a rail from a groove.
BRIGHTNESS ADJUSTMENT
By rotating the “R” handle you may adjust
the reticle’s brightness. Adjustment could
be easily seen if you look trought the scope
while adjustement.
WINDAGE AND ELEVATION
The vertical and horizontal adjustments for
the Aries can be achieved by turning the
elevation and windage adjustment mecha-
nisms (remove dust caps first). Each click
equals to 1/8 inches at 100 yards. When
reaching the maximum of rotation do not
use force.
FOCUSING
To focus your riflescope you will need to
adjust the diopter first thing. Simply turn the
diopter clockwise until it stops. Then, while
looking through the diopter at a subject,
slowly turn the diopter back counter clock-
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 are both sharp. 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.
