(Music Navigator): Use the music navigator
feature to play MP3 files on the CD-R or CD-RW in order
by artist or album. Press the pushbutton located below
the music navigator label. The player scans the disc to
sort the files by artist and album ID3 tag information. It
can take several minutes to scan the disc depending on
the number of MP3 files recorded to the CD-R or CD-RW.
The radio can begin playing while it is scanning the disc
in the background. When the scan is finished, the CD-R
or CD-RW begins playing again.
Once the disc has been scanned, the player defaults to
playing MP3 files in order by artist. The current artist
playing is shown on the second line of the display
between the arrows. Once all songs by that artist are
played, the player moves to the next artist in alphabetic
order on the CD-R or CD-RW and begin playing MP3 files
by that artist. If you want to listen to MP3 files by another
artist, press the pushbutton located below either arrow
button. You will go to the next or previous artist in
alphabetic order. Continue pressing either button until the
desired artist is displayed.
