Notes
• Be sure to finalize the disc before using on the unit.
• When naming an MP3 file, be sure to add the file
expansion ".mp3" to the file name.
• If you play a high-bit-rate MP3, such as 320 kbps,
sound may be intermittent.
• During playback of a VBR (variable bit rate) MP3 file
or fast-forward/reverse, elapsed playing time may
not display accurately.
• When the disc is recorded in Multi Session, only the
first track of the first session format is recognized
and played (any other format is skipped). The
priority of the format is CD-DA, ATRAC CD and
MP3.
– When the first track is a CD-DA, only CD-DA of the
first session is played.
– When the first track is not a CD-DA, an ATRAC CD
or MP3 session is played. If the disc has no data in
any of these formats, "NO Music" is displayed.
