- 

remove the cover 8 and insert the battery as shown on the 
cover of scope; 

- 

screw up the cover 8; 

- 

turn on the switch 7. 

In 3-4 seconds the eyepiece field of view should begin to 
gleam with yellow-green light and red aiming reticle; 
- 

adjust the optimal contrast of aiming reticule by means of 
hand wheel 17; 

- 

if reticle is switched on but is extinct with the lit screen, 
the battery should be replaced with operable one; 

 
Warning: the reticle extinction indicates the discharge of 
battery. 
The central peak of reticle is assigned for sighting. The 
vertical markers on each side of central peak can be used for 
lateral deflection at moving target or strong wind. The scope 
should be aligned to the weapon by means of zeroing. Zeroing 
is carried out in the daytime and with the light filter cap put on 
only, in the following order: 
- 

set the target of approximately 1x1 m at the range 100 m; 

- 

make the 3-4 shoots from rest at regular aiming of the 
peak to centre of target; 

- 

determine the mean point of impact by holes placement. 

If mean point of impact disagrees to aiming point more than 
by 3 cm the scope alignment is needed. Align the scope by 
mean of screws for vertical and horizontal adjustments. The 
turn by one click corresponds to shift of mean point of impact 
by 3 cm at the range of 100 m.
