(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
could 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 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 alphabetical order on
the CD-R or CD-RW and begins playing MP3 files by that
artist. To listen to MP3 files by another artist, press the
pushbutton located below either arrow button. The next or
previous artist in alphabetical order plays. Continue
pressing either button until the desired artist is displayed.
To change from playback by artist to playback by album,
press the pushbutton located below the Sort By label.
From the sort screen, push one of the buttons below
the album button. Press the pushbutton below the
back label to return to the main music navigator screen.
