Settings for compression software and writing
software
It is recommended that when compressing an
audio file you select the "constant" size of "128bps"
for the transfer bit rate setting in the compression
software. Select the "Disc at Once" setting when
recording data by filling an empty disc at one time.
File names
Please add the appropriate ".MP3" or "WMA"
extension to audio files. Files that do not have either
of these extensions cannot be played.
Do not add the above extensions to files that are not
audio files. Should you add one of these extensions, the
unit will mistakenly recognize the file as an audio file,
thus producing a loud noise that could damage the
speakers.

This unit can display the following track information:
track name, artist name and album name.
Information is displayed using Roman letters and
Arabic numerals.
• Track information recorded using v1.0, 1.1 or 2.3
standards for the MP3 ID3 Tag is displayed using
a maximum of 30 characters.
