FOCUSING
To focus the NVSG1/ NVSG2IA you need to adjust the diopter first. Simply turn the diopter clockwise
until it stops. Then concentrate on any object and slowly turn the diopter back counter clockwise
until the grain in the image is sharp.
When you are under low-light conditions and the daylight filter is off you may focus the front lens for
the image to be sharp. The diopter is not to be adjusted.
NOTE: The front lens should be readjusted for viewing objects at different distances.
You scope has ability to focus either long range or short.
Next, focus the front lens by rotating the knob 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:To remove the front lens to clean, you must unlock the above set screw.
MOUNTING
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 positions already available on the weav-
er 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 mount-
ing this rail. Besides it is possible to change the posi-
tion of the riflescope 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 aperture 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.
