Pulsar DIGISIGHT N750A Betriebsanleitung Seite 9

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.
Technical maintenance should be done at least twice a year, includes the
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
solvent.
Inspect the eyepiece lens, the objective lens and the IR illuminator and
gently blow off any dust and sand, and clean using lens cleaner and a soft
cloth; see section 6 "GUIDELINES FOR OPERATION".
Always store the unit in its carrying case in a dry, well-ventilated space. For
prolonged storage, remove the batteries.
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 the manufacturer.

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.
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 2-3 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.
Check focusing of the scope in night
conditions.
Activate the remote according
to instructions in section 15.
Install a new CR2032 battery.
