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.
