•
Make sure playlists have a .mp3 or .wpl extension
(other file extensions might not work).
•
Minimize the length of the file, folder or playlist
names. Long file, folder, or playlist names, or a
combination of a large number of files and folders,
or playlists can cause the player to be unable to
play up to the maximum number of files, folders,
playlists, or sessions. If you wish to play a
large number of files, folders, playlists, or sessions,
minimize the length of the file, folder, or playlist
name. Long names also take up more space on the
display, potentially getting cut off.
•
Finalize the audio disc before you burn it. Trying to
add music to an existing disc can cause the disc
not to function in the player.
Playlists can be changed by using the
a
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.
Root Directory
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.
Empty Directory or Folder
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.
No Folder
S c c T
and
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.
