Playlists can be changed by using the
folder buttons, the knob, or the SEEK arrows. An
MP3/WMA CD-R or CD-RW that was recorded using no
file folders can also be played. If a CD-R or CD-RW
contains more than the maximum of 50 folders,
50 playlists, and 255 files, the player lets you access
and navigate up to the maximum, but all items over the
maximum cannot be accessed.
The root directory of the CD-R or CD-RW is treated as a
folder. If the root directory has compressed audio files,
the directory displays as F1 ROOT. All files contained
directly under the root directory are accessed prior to
any root directory folders. However, playlists (Px) are
always accessed before root folders or files.
If a root directory or a folder exists somewhere in the
file structure that contains only folders/subfolders and
no compressed files directly beneath them, the player
advances to the next folder in the file structure that
contains compressed audio files. The empty folder
does not display.

When the CD contains only compressed files, the files
are located under the root folder. The next and previous
folder functions do not display on a CD that was
recorded without folders or playlists. When displaying
the name of the folder the radio displays ROOT.
When the CD contains only playlists and compressed
audio files, but no folders, all files are located under the
root folder. The folder down and the folder up buttons
search playlists (Px) first and then goes to the root
folder. When the radio displays the name of the folder
the radio displays ROOT.
Tracks recorded to the CD-R or CD-RW play in the
following order:
Play begins from the first track in the first playlist
and continues sequentially through all tracks in
each playlist. When the last track of the last playlist
has played, play continues from the first track of
the first playlist.
Playlists can be changed by pressing the
