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 4 pages are
shortened. The display does not
show parts of words on the last
page of text and the extension of
the file name is not displayed.
Preprogrammed Playlists
CDs that have preprogrammed
playlists reated using WinAmp ,
MusicMatch , or Real Jukebox
software can be accessed; however,
there is no playlist editing capability
using the radio. These playlists are
treated as special folders containing
compressed audio song files.
Playlists that have an .m3u or .pls
file extension and are stored on a
USB device may be supported by
the radio with a USB port.
Playlists can be changed by using
S
the softkeys below the
T
tabs, the knob, the
SEEK button, or the
SEEK button. An MP3 CD-R or
CD-RW that has been recorded
without using file folders can be
played. If a CD-R or CD-RW
contains more than the maximum of
50 folders, 15 playlists, and
512 folders and files, the player
allows access and navigates up to
the maximum, but all items over the
maximum are not accessible.
