Notes On Playing MP3 Files
The radio can play MP3 files, however, acceptable MP3
file recording media and formats are limited. When
writing MP3 files, pay attention to the following restric-
tions.
Supported Media (Disc Types)
The MP3 file recording media supported by the radio are
CD-ROM, CD-R and CD-RW.
Supported Medium Formats (File Systems)
The medium formats supported by the radio are ISO 9660
Level 1 and Level 2 and includes the Joliet extension.
When reading discs recorded using formats other than
ISO 9660 Level 1 and Level 2, the radio may fail to read
files properly and may be unable to play the file nor-
mally. UDF and Apple HFS formats are not supported.

204 UNDERSTANDING YOUR INSTRUMENT PANEL

²Maximum number of files: 255
²Maximum number of folders: 100
²Maximum number of characters in file/folder names:
²Level 1: 12 (including a separator9.9and a
3-character extension)
²Level 2: 31 (including a separator9.9and a
3-character extension)
Multisession disc formats are supported by the radio.
Multisession discs may contain combinations of normal
CD audio tracks and computer files (including MP3 files).
Discs created with an option such as9keep disc open after
writing9are most likely multisession discs. The use of
multisession for CD audio or MP3 playback may result in
longer disc loading times.
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.

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
supported.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:
²Media - CD-RW media may take longer to load than
CD-R media
²Medium formats - Multisession discs may take longer
to load than non-multisession discs
²Number 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.
