File names
Only files with the MP3IWMAlAAC file extension ".mp3", ".wma" , ".m4a" can be recognized as MP3/
WMAlAAC and played. Be sure to save MP3 files with the ".mp3" file extension. Be sure to
WMA
files with the ".wma" file extension. Be sure to save AAC files with the ".m4a" file extension. The
"MP" letters
of
the file extension will be recognized whether entered as uppercase letters or
lowercase letters.
If the ".mp3", ".wma", ".m4a" file extension is attached to a file other than an MP3IWMAlAAC file,
that file will be mistakenly recognized by the main unit as an MP3IWMAlAAC file and played,
resulting
in
loud noise output that can damage the speakers. Be sure to avoid attaching the ".mp3",
".wma", ".m4a" file extension to files that are not MP3IWMAlAAC files.
