following steps:

Clean the outside metal and plastic surfaces from dust, dirt and moisture;

wipe the scope with a soft lint free cloth.

Clean the battery compartment's electric contact points using an oil-free

The riflescope will not focus.

The riflescope is not mounted

securely or the mount was not

fixed with thread sealant.

Wrong settings.

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 small displacement 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.

The riflescope cannot be

started with wireless remote

control.

Remote control is not activated.

Battery is low.

Activate the remote according

to instructions in section 15.

Install a new CR2032 battery.

The scope is used in day light at

long working distance

Check focusing of the scope in night

conditions.

After the built-in laser IR

Illuminator is activated, you

may see a slightly grainy,

non-uniform pattern which

does not impact detection

range and efficiency of

observation.

This is not a defect.

This is normal for eye safe

laser illuminators.

problem

possible cause(s) сorrective action

The riflescope

will not turn on.

The reticle is blurred

and cannot be focused

with the dioptre knob.

With a crisp image of the

reticle, the image of the

observed target that is at

least 30 m away is blurred.

Batteries have been wrongly

installed.

Oxidized contact points in the battery

compartment due to “leaky” batteries

or contact points becoming exposed

to a chemically-reactive solution.

The batteries are empty.

The dioptre cannot be adjusted

to your eyesight.

Dust and condensate are covering

the outside optical surfaces after

the riflescope was brought in from

the cold into a warm environment,

for example.

Reinstall the batteries with

the correct polarity orientation.

Clean the battery compartment,

focusing on the contacts.

Install fresh batteries.

If you wear prescription glasses with

a range of +/- 4, keep glasses on when

looking through the eyepiece.

Clean the lens surfaces with a blower

and soft lens cloth.

Let the riflescope dry by leaving it in a

warm environment for 2-3 hours.

It is recommended that you inspect the riflescope before every use. Make sure

to check for the following:

Visually inspect that the unit is free from any physical damage; cracks,

dents or signs of corrosion which may disqualify it from proper use.

Check the sturdiness and proper fit of the mounting system.

Ensure that the objective lens, eyepiece and the IR illuminator are free of

cracks, grease spots, dirt, water stains and other residue before use.

Visually inspect the condition of the battery and the battery compartment;

the battery should be free of electrolyte and oxidation residue, especially

where the battery makes contact with metal.

Verify the proper function of the following: selector switch, display

brightness adjustment knob and other operation buttons.

Verify the smoothness of the objective lens focus knob, dioptre focus knob.

Residual “ghost image” after

reticle change can be noticed

on the display.

This effect attributes to the peculiarity

of OLED display technology.

This is not a defect.

Peculiarities of CCD array

CCD arrays employed in Pulsar digital night vision devices, feature high quality. However certain

pixels (or groups of pixels) with increased luminosity (lighter or darker) are allowed. These defects

can be seen when conducting observation not only in the nighttime but in the day time too, especially

if Sum Light™ function is active. Presence of light and dark pixels and other minor defects of a CCD

array (up to 4%) are acceptable in accordance with regulations of the array producer.

Visibility on the screen of light pixels also depends on the type of CCD array, heating temperature

during operation.
