Subject to modification
This Compact Disc changer compiies with radio
interference requirements as iaid down in EC
reguiations.
Insufficientfamiliarity with the combination of a new
product and new discs may lead to faults arising
during use. These are generally caused by simple
errors in operation or external factors.
It is perhaps useful to checkthe points listed below
and where possible remedy these before taking
your changer for repair.
- The transit clamps have not been removed.
- Condensation has formed on the lens of the laser
due to a dramatic change in temperature. This will
disappear automatically after some time.
- There is a foreign object in the disc tray.
- The disc has not been inserted with the printed
side facing downwards or there is no disc in the
tray.
- The disc is dirty, badly scratched or warped.
- The changer has been connected to the PHONO
input of the amplifier.
If the fault remains, try to clear it by switching the
changer off and on.
If this also fails to help, do not continue experiment­
ing, but remove the mains plug from the wall socket
and consult your dealer.
Certain faults may be caused by a disc. In order to
help determine the precise cause, take the disc with
which the fault occurred with you when you take the
changer for repair.
Under no circumstances shouid you repair the
changer yourself, as this will invalidate the guar­
antee!
