PROBLEM
The aiming point shifts after
firing rounds.
The riflescope will not focus.
Poor image quality
Image is over-exposed.
Barely visible texture which
does not hinder detec-
tion range or efficiency of
observation can be noticed
on the display after the extra
laser IR Illuminator (AL915) is
activated.
Stripes appear on the display
or image disappears.
There are several light or black
dots (pixels) on riflescope's
display or sensor.

POSSIBLE CAUSE
The riflescope is not mounted
securely or the mount was not
fixed with thread sealant.
Wrong settings.
The riflescope is used in the
daytime at long distances.
Problems described may arise in adverse weather conditions
(snow, rain, fog etc.).
Lens cover is open.
This effect is due to the peculiarity of operation of IR Illumina-
tors and it's not a defect.
The riflescope has accumu-
lated static charge during
operation.
Presence of dots is caused by peculiarities of sensor or display
production technology and is not a defect.
СORRECTIVE ACTION
Check that the riflescope
has been securely mounted,
make sure that the same
type and calibre bullets are
being used as when the scope
was initially zeroed; if your
riflescope was zeroed during
the summer, and is now being
used in the winter (or the
other way round), a slight shift
of the aiming point is possible.
Adjust the riflescope according
to the instructions given in
the section 9 "Operation"
and check the surfaces of the
eyepiece and objective lenses
and clean them if necessary
from dust, condensation,
frost, etc; to prevent fogging in
cold weather, apply a special
anti-fog solution.
Check focusing in the
nighttime.
Use the riflescope with a
closed lens cover.
As soon as the impact of the
static charge is over, the de-
vice may reboot automatically;
alternatively please turn off
and restart the device.
