Caution for DualDisc playback
• The Non-DVD side of a "DualDisc" does not
comply with the "Compact Disc Digital Audio"
standard. 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.
• When a disc is inserted upside down, "PLEASE"
and "EJECT" appear alternately on the display.
Press 0 to eject the disc.
• 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.
• MP3 and WMA "tracks" (words "file" and "track"
are used interchangeably) are recorded in
"folders."
• While fast-forwarding or reversing on an MP3
or WMA disc, you can only hear intermittent
sounds.
Playing a CD-R or CD-RW
• Use only "finalized" CD-Rs or CD-RWs.
• This unit can only play back files of the same
type as those detected first if a disc includes
both audio CD (CD-DA) files and MP3/WMA
files.
• This unit can play back multi-session discs;
however, unclosed sessions will be skipped
while playing.
18 ENGLISH
• Some CD-Rs or CD-RWs may not play back on
this unit because of their disc characteristics,
or for the following reasons:
– Discs are dirty or scratched.
– Moisture condensation has occurred on the
lens inside the unit.
– The pickup lens inside the unit is dirty.
– The files on the CD-R/CD-RW are written
using the "Packet Write" method.
– There are improper recording conditions
(missing data, etc.) or media conditions
(stained, scratched, warped, etc.).
• CD-RWs may require a longer readout time
since the reflectance of CD-RWs is lower than
that of regular CDs.
• Do not use the following CD-Rs or CD-RWs:
– Discs with stickers, labels, or a protective seal
stuck to the surface.
– Discs on which labels can be directly printed
by an ink jet printer.

or high humidity may cause malfunctions or
damage to the unit.
