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.
