Playback may not occur in the above
hierarchy depending on the audio unit.
The folder order is automatically
l
assigned and this order cannot be
optionally set.
Any folder without an MP3 file will be
l
ignored. (It will be skipped and the
folder number will not be displayed.)
MP3 files not conforming to the MP3
l
format containing both header frames
and data frames will be skipped and
not played.
This unit will play MP3 files that have
l
up to eight levels. However, the more
levels a disc has, the longer it will take
to initially start playing. It is
recommended to record discs with two
levels or less.
A single disc with up to 512 files can
l
be played and a single folder with up to
255 files can be played.
When naming an MP3 file, be sure to
l
add an MP3 file extension (.mp3) after
the file name.
