Maximum Writing Speed and Bit Depth
The maximum speed of the CD ROM burner accepted by the RFX units is 12X. The max-
imum bit rate range possible is 32kb/sec–320kb/sec. For best performance of scrolling
display, before creating a file system in your CDR burning program, select the CD layout
properties menu and file system tabs. The JOLIET file format is preferred, this allows a
maximum of 24 upper and lowercase scrolling characters to be displayed. The use of
ISO9660 file format and selecting the Long File Names option on your PC will work,
however, this allows a only a maximum of 16 uppercase scrolling characters to be dis-
played.
NOTE: Make sure that when a MP3 CD is burned that it is formatted as a data disc and
NOT as an audio disc.
Directory Structure
The MP3 directory is set up in three levels and
is comprised of three components: (1) the Root,
(2) Folders, and (3) Songs. Songs are played in
the order and level in which they are located.
As shown in the diagram to the right, all songs
in Level 2 are played before the songs con-
tained in Level 3 or lower. These levels are
descriptive of the function of having songs in
folders and sub-folders. Any song in a level
below Level 3 is treated as though it were in
Level 3, but will play in the level order as
shown. The songs in the diagram at the right
are numbered in the order they will play.
NOTE: Pressing the ROOT button will take you
to the root directory. Pressing ROOT a
second time will take you back where you started.
