(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.
