Notes
• Depending on the quality of the disc and/or the condition of the
recording device, it may take a while for playback to start. It is
also possible playback may not start at all.
• On a disc that has MP3 files, do not save files in other formats
and do not make unnecessary folders.
• Be sure to add the file extension "mp3" to the file name.
However, if you add the extension "mp3" to a file other than
an MP3 file, the player will not be able to recognize the file
properly.
• To compress a source in an MP3 file, we recommend setting
the compression parameters to "44.1 kHz," "128 kbps," and
"Constant Bit Rate."
• To record up to the maximum capacity, set the writing software
to "halting of writing."
