prolonged storage, remove the batteries.

TROUBLESHOOTING

Listed below are some potential problems that may occur when using the scope.
Carry out the recommended checks and troubleshooting steps in the order
listed. Please note that the table does not list all of the possible problems. If the
problem experienced with the scope is not listed, or if the suggested action
meant to correct it does not resolve the problem, please contact your seller.
PROBLEM POSSIBLE CAUSE(s)
The riflescope will not turn on. 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 or
one of batteries is faulty.

СORRECTIVE ACTION
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 4 hours.
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 scope is used in day light at
long working distance.
The riflescope cannot be started Remote control is not activated.

that prevents signal transmission.
The unit is not held steadily when
measuring.
Distance to the object exceeds
400m.
Low reflection ratio (i.e. leaves of
trees).
Large measurement error. Inclement weather conditions
(rain, mist, snow).
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 SumLight™ 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 sensor producer.
Visibility on the screen of light pixels also depends on the type of CCD array, heating
temperature during operation.
Check focusing of the scope in night
conditions.
Activate the remote according to
instructions in section 16.
Install a new CR2032 battery.
Charge the power supply
(if required).
If it's necessary, unbend
the pin to ensure electric contact.
This is not a defect.
Make sure that the lenses are not
blocked by your hand or fingers.
Do not stress the unit when
measuring.
Choose an object at a distance
longer than 400m.
Choose an object with a higher
reflection ratio.
