Maintenance
This receiver is a precision instrument that is
constructed using extremely accurate
technology. Dust and friction can affect the
pickup lens and disc drive and can impair the
image quality. In extreme situations, neither
video nor audio can be played back. To obtain
optimum picture quality, the DVD receiver should
be checked (cleaned and some parts replaced)
every 1,000 hours. Note that this period varies
depending on the environment (temperature,
humidity, dust, and so on) in which the receiver
is used.
If the DVD receiver is not being used, the disc
tray should remain closed to protect the
mechanism against dust. However, it is still
possible for the vents to become dirty from dust
or the lens could get covered by a thin, hardly
visible, film. The DVD receiver is then no longer
able to scan the inserted disc. In this case, you
need to have the lens cleaned by a technician
(Do not attempt to clean the pickup lens by
yourself).
Electronic components are subject to a natural
aging process and the mechanical parts are
subject to normal wear. Dust particles inside the
device may also cause faults to occur. For
example, problems may occur when the laser
lens get dirty.
Consult your authorized dealer in the case of
any problems.
You should only use the original packaging to
transport the components.
Cleaning components
Before cleaning, switch off the DVD receiver.
Clean all components using a wet cloth or a little
synthetic cleaner. Solvents, spirits, detergents,
and similar cleaners can damage the surfaces of
your home theater system components.
Care and handling of discs
Handling discs
Do not touch the playback side of the disc. Hold
the disc by the edges so that fingerprints do not
get on the surface. Never stick paper or tape on
the disc.
Storing discs
After playing, store the disc in its case. Do not
expose the disc to direct sunlight or sources of
heat and never leave it in a parked car exposed
to direct sunlight.
Cleaning discs
Fingerprints and dust on the disc can cause
poor picture quality and sound distortion. Before
playing, clean the disc with a clean cloth. Wipe
the disc from the center out.
Do not use strong solvents such as alcohol,
benzine, thinner, commercially available
cleaners, or anti-static spray intended for older
vinyl records.
