Therefore, the use of Non-DVD side of a DualDisc
on this product may not be recommended.
General
• This unit has been designed to reproduce CDs/CD
Texts, and CD-Rs (Recordable)/CD-RWs (Rewritable)
in audio CD (CD-DA), MP3 and WMA formats.
• If you change the source while listening to a disc,
playback stops. Next time you select “CD” as the
playback source, playback will start from where it
had been stopped previously.
• If the ejected disc is not removed within 15 seconds,
it is automatically inserted into the loading slot again
to protect it from dust. Playback starts automatically.
