Using an MP3
Format
Radios that have the capability of playing MP3's can
play .mp3 or .wma files that were recorded onto a CD-R
or CD-RW disc. Radios that have a USB port can
play .mp3 and .wma files that are stored on a USB
storage device as well as AAC files that are stored on
an iPod
®.
Compressed Audio
The radio can play discs that contain both
uncompressed CD audio and MP3 files. If both formats
are on the disc, the radio reads all MP3 files first, then
the uncompressed CD audio files.
CD‐R or CD‐RW Supported File and Folder
Structure
The radio supports:
.Up to 50 folders.
.Up to 8 folders in depth.
.Up to 50 playlists.
.Up to 255 files.

Root Directory
The root directory is treated as a folder. Files are stored
in the root directory when the disc or storage device
does not contain folders. Files accessed from the root
directory of a CD display as F1 ROOT.
Empty Folder
Folders that do not contain files are skipped, and the
player advances to the next folder that contains files.
Order of Play
Tracks 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 has been 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. The display does not show parts of
words on the last page of text and the extension of the
filename is not displayed.

Preprogrammed Playlists
CDs that have preprogrammed playlists that were
created 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.
