Supported MP3 File Formats
The radio will recognize only files with the *.mp3 exten-
sion as MP3 files. Non-MP3 files named with the *.mp3
extension may cause playback problems. The radio is
designed to recognize the file as an invalid MP3 and will
not play the file.
When using the MP3 encoder to compress audio data to
an MP3 file, the bit rate and sampling frequencies in the
following table are supported. In addition, variable bit
rates (VBR) are also supported. The majority of MP3 files
use a 44.1 kHz sampling rate and a 192, 160, 128, 96 or
VBR bit rates.MPEG Specifi-

ID3 Tag information for artist, song title and album title
are supported for version 1 ID3 tags. ID3 version 2 is not
supported by the radios.
Playlist files are not supported. MP3 Pro files are not

Playback of MP3 Files
When a medium containing MP3 data is loaded, the
radio checks all files on the medium. If the medium
contains a lot of folders or files, the radio will take more
time to start playing the MP3 files.
Loading times for playback of MP3 files may be affected
by the following:
•Media - CD-RW media may take longer to load than
CD-R media
•Medium formats - Multisession discs may take longer
to load than non-multisession discs
•Number of files and folders - Loading times will
increase with more files and folders
To increase the speed of disc loading, it is recommended
to use CD-R media and single-session discs. To create a
single-session disc, enable the Disc at Once option before
writing to the disc.
