With a crisp image of
the reticle, the image of
the observed target that
is at least 30 m away is
blurred.
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
intensifier 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.
The total battery charge
is less than 2.0V.
Install fresh battery.
Distinct black dots
or specs 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.
