Problem
Possible cause(s)
Corrective action
The batteries have been
installed incorrectly.
Reinstall the batteries with the
correct polarity orientation.
The total battery charge is less
than 2.0V.
Install fresh batteries.
The riflescope
does not turn on.
Oxidized contact points in the
battery compartment due to
“leaky” batteries or contact
points becoming exposed to
a chemically-reactive solution.
Clean the battery compartment,
focusing on the contact points.
The red reticle is blurred
and cannot be focused
with the diopter knob.
The diopter cannot be adjusted
to your vision.
If you wear prescription glasses
with a range of +/- 5, keep glasses
on when looking through the
eyepiece.
Dust and moisture are covering
the outside optical surfaces.
Clean the lens surfaces with a soft
cotton tissue or cloth.
Moisture is on the inside of the
objective and the eyepiece
lenses, or is on the optical
surfaces of the electronic-
optical converter and may be
caused by the unit fogging up
due to a rapid change in
temperature; when the device is
brought in from the cold into a
warm environment, for
example.
Let the riflescope dry by leaving it
in a warm environment for 4
hours.
With a crisp image
of the reticle, the image
of the observed target that
is at least 30 m away
is blurred.
The total battery charge is less
than 2.0V.
Install fresh batteries.
Distinct black dots or specks
on the screen.
The dots on the screen are
cosmetic blemishes in the
intensifier tube and are a by-
product of the manufacturing
process; they do not in any way
affect the life or performance
of the unit, and if there is dust
on the lens, please clean
according to the instructions.
No need to take corrective action
or return the device.
The scope or the
IR illuminator do not turn
off via the selector switch
The scope is turned on via the
remote control.
Turn off the scope and the IR
illuminator using the remote
control.
