Please note that due to “piracy” concerns, some record companies/pressing plants are creating disks that

performance we recommend all home-generated CDs intended for playback on
not
MP3, WAV, etc.) on good quality household brand AUDIO grade CD-Rs.
Remember - the most vulnerable part of a CD playing system is the disc itself. The most likely cause of a disc not playing is that
the disc itself is faulty, scratched or simply dirty. Never open the case of the unit yourself, as this will invalidate the guarantee. If
