This product contains a PHILIPS CD mechanism, which complies with the PHILIPS/SONY red book
CDDA standard. It is guaranteed to play all disks similarly marked without any problems.
Please note that due to “piracy” concerns, some record companies/pressing plants are creating disks that
do not adhere to this standard. Such disks may –or- may not play in some –or- all CD player products of
any manufacturer. We advise caution in using these disks, as the information contained therein has been
deliberately manipulated and can cause audio degradation and/or playability problems.
We also advise caution with using cheap CD-R, and/or CD-RW disks for audio, and to ensure all home-generated CDs intended for
playback on this unit are recorded as CDDA AUDIO CDs (i.e. not MP3, WAV, AAC etc.) on good quality media.
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 none of the above actions affect
a cure, please contact your dealer or Musical Fidelity service agent.
