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.

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 clockwise 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.
ir illuminATion
Infra-red (IR) Illuminators are common for night vision technology. The IR light greatly
enhances the performance of your scope, while remaining almost totally invisible to the
naked eye. In dark environment, power up the scope. Now, find a scene and examine it
without the IR on then with IR powered up. Note the difference in illumination. It is important
to remember that the IR illuminator is simply an infra red light source, and like any light
source it may loose its effectiveness over a great distance.
To fix the IR Illuminator to the riflescope screw the thumb screw on the IR into the thread on
the scope. To switch the IR on and to adjust the brightness rotate the rheostat located on the
side of the Illuminator. The changes of adjustment could be observed while looking through
the scope. The IR is off when the mark on the rheostat coincides with "0" on the scale.
NOTE: The riflescope could be equipped with digitally controlled IR.
The IR illuminator control buttons are located on its side. To switch the Digital IR illuminator
on/off press "+" and "-" buttons simultaneously. When the IR illuminator is switched on
you can see the green LED lit. By pushing the buttons "+" and "-" you may adjust the IR
brightness.
The IR beam is focusable to change the field of coverage. To change the beam width slightly
turn the IR lens.
