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.”
