Order of Play
Tracks recorded to the CD-R are played 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.
•
Play begins from the first track in the first
folder and continues sequentially through
all tracks in each folder. When the last track of
the last folder has played, play continues
from the first track of the first folder.
When play enters a new folder, the display does
not automatically show the new folder name unless
the folder mode was chosen as the default
display. The new track name displays.

File System and Naming
The song name that displays is the song name
that is contained in the ID3 tag. If the song name is
not present in the ID3 tag, then the radio displays
the file name without the extension (such
as .mp3) as the track name.
Track names longer than 32 characters or
four pages are shortened. Parts of words on the
last page of text and the extension of the filename
does not display.
Preprogrammed Playlists
Preprogrammed playlists that were created using
WinAmp™, MusicMatch™, or Real Jukebox™
software, can be accessed, however, they cannot
be edited using the radio. These playlists are
treated as special folders containing compressed
audio song files.
