The radio uses the following limits for file systems:
• Maximum number of directory levels: 8
• Maximum number of files: 255
• Maximum number of folders: 100
• Maximum number of characters in file/folder names:
• Level 1: 12 (including a separator . and a three-
character extension)
• Level 2: 31 (including a separator . and a three-
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 as keep
disc open after writing are most likely multisession
discs. The use of multisession for CD audio or MP3/
WMA playback may result in longer disc loading times.
UNDERSTANDING YOUR INSTRUMENT PANEL 351
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
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.
