Sony CDX-MP30 Mode D'emploi page 8

Notes
• With formats other than ISO 9660 level 1 and
level 2, folder names or file names may not be
displayed correctly.
• When naming, be sure to add the file extension
".MP3" to the file name.
• If you put the extension ".MP3" to a file other
than MP3, the unit cannot recognize the file
properly and will generate random noise that
could damage your speakers.
• The following discs take a longer time to start
playback.
— a disc recorded with complicated tree
structure.
— a disc recorded in Multi Session.
— a disc to which data can be added.
• If you play a high-bit rate MP3 file such as 320
kbps, sound may be intermittent.
Cautions when playing a disc that is recorded in
Multi Session
• When the first track of the first session is audio
CD data:
Only audio CD data is played back.
Non-audio CD data/MP3 file information (track
number, time, etc.) is displayed with no sound.
• When the first track of the first session is not
audio CD data:
— If an MP3 file is in the disc, only MP3 file(s)
play back and other data is skipped. (Audio CD
data is not recognized.)
— If no MP3 file is in the disc, "NO MUSIC" is
displayed and nothing is played back. (Audio
CD data is not recognized.)

The playback order of the MP3 files
The playback order of the folders and files is as
follows:
1
1
2
2
6
6
7
Tree 1 Tree 2 Tree 3
(root)
Notes
• A folder that does not include an MP3 file is
skipped.
• When you insert a disc with many trees, it takes a
longer time to start playback.
We recommend that you make only one or two
trees for each disc.
• Maximum folder number: 150 (including root
folder and empty folders)
• The maximum number of MP3 files and folders
that can be contained in a disc: 302
When a file/folder name contains many
characters, this number may become less than
302.
• The maximum number of trees which can be
played is 8.
Tip
To specify a desired playback order, before the
folder or file name, input the order by number
(e.g., "01," "02"), then record contents onto a disc.
(The order differs depending on the writing
software.)
