Important notes on the MP3 file

fixed 128 kbps (Constant Bit Rate).
÷ Sampling frequency is 44.1 kHz.

Sequence of playing MP3 files
MP3 files will be played in the sequence that the writing software had recorded. Therefore, it may be different between
the sequence that you want to record and the sequence of playing. For some writing software, input "01" ~ "99", for
example, before the file names in the sequence of playing and then record into a CD-R, etc, sometimes you may setup
the sequence of playing.
Writing files onto a medium
When a medium containing MP3 data is loaded, the unit checks all the files on the medium. If the medium contains a lot
of folders or non-MP3 file, therefore, it takes a long time until the unit starts playing MP3 file. In addition, it may take
time for the unit to move to the next MP3 file or a file search or folder search may not be performed smoothly. You
should not write non-MP3 file or unneeded folders along with MP3 file on the medium.
