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.
The radio uses the following limits for file systems:
²Maximum number of directory levels: 8
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/
WMA 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/
WMA playback may result in longer disc loading times.
If a disc contains multi formats, such as CD audio and
mp3/wma tracks, the radio will only play the mp3/wma
tracks on that disc.
Supported MP3/WMA File Formats
The radio will recognize only files with the *.MP3/WMA
extension as MP3/WMA files. Non-MP3/WMA files
named with the *.MP3/WMA extension may cause play-
back problems. The radio is designed to recognize the file
as an invalid MP3/WMA and will not play the file.
When using the MP3/WMA encoder to compress audio
data to an MP3/WMA file, the bit rate and sampling
224 UNDERSTANDING YOUR INSTRUMENT PANEL

frequencies in the following table are supported. In
addition, variable bit rates (VBR) are also supported. The
majority of MP3/WMA files use a 44.1 kHz sampling rate
and a 192, 160, 128, 96 or VBR bit rates.

Playback of MP3/WMA Files
When a medium containing MP3/WMA 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/WMA files.
Loading times for playback of MP3/WMA 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
