PLAYING AN MP3 DISC/USB
The MP3 player will play files recorded on a CD-R up
to 700 MB or on a USB stick of up to 1 GB. Files can
be recorded at a variable bit rate or the following
fixed-bit rates: 32 kpbs, 40 kpbs, 64 kpbs, 80 kpbs,
96 kpbs, 112 kpbs, 128 kpbs, 160 kpbs, 192 kpbs,
224 kpbs, 256 kpbs, and 320 kpbs. Both single and
multi-session discs will play. Song title, artist name
and album are available when discs are recorded
using ID3 tags, versions 1 and 2.
Files supported on USB sticks: MP1, MP2, MP3
(VBR), WMA (ver 9 and VBR) and ACC (MPEG4 and
M4A).
The MP3 player is able to read and play a maximum
of 50 folders and playlists. Long files, folders or a
combination can reduce the number of files and fold-
ers that can be played. If a large number of files or
folders are to be played, minimize the length of the
files and folders. The MP3/WMA recorded files with-
out file folders can also be played. The system can
support up to 11 levels of folder nesting. If a disc con-
tains more than 50 folders or 11 folder levels, the
player will only allow access and navigate the maxi-
mum number and will ignore additional items.

Root Directory

The root directory is treated as a folder. If the root
directory has compressed audio files, the directory is
displayed as ROOT. All files contained directly under
the root directory are accessed prior to any root
directory folders.

Empty Directory or Folder

If there is a root directory or folder in the file structure
that contains empty
advances to the next folder in the file structure that
contains compressed audio files. The empty folder
will not be displayed or numbered.

No Folder

When a disc contains only compressed files, the files
are located under the root folder. The next and previ-
ous folder functions have no function on a CD
recorded without folders. When displaying the name
of the folder, the radio displays ROOT.

File Name Display

A song title is displayed when contained in the ID3
tag. Titles longer than 8 characters scroll at a rate of
8 characters every 2 seconds until the entire name is
shown.
