FAULTS AND THEIR LIKELY CAUSES
Although the greatest care has been taken in the manufacture of
this Compact Disc player, the possibility remains that faults could
appear during use or that the player fails to function to your
compiete satisfaction.
The cause, however, will certainly not always be found in the
piayer itself. External factors, and the fact that it takes time to
become accustomed to the whole concept of the new product
and the new discs, can aiso play a role.
To save you unnecessary calls on your dealer or our Service
Organisation, we have compiled a list of possibie faults and their
causes. To even mention some of these causes, such as those
to do with the mains suppiy, may perhaps seem excessive. Our
experience shows, however, that they are easily overlooked as
sources of trouble.
If, by using this list, you do not succeed in solving the probiem,
stop your investigation. Disconnect the mains plug and contact
your dealer.
Under no circumstances should you open up the player; this will
invalidate all rights under the guarantee!
