Sony CDX-M9905X Operating Instructions (English, Español, Français) Operating Instructions Manual page 9

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.
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, "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
6
Tree 1 Tree 2
Tree 3
(root)
Notes
• A folder that does not include an MP3 file is skipped.
• Maximum folder number: 150 (including root folder
and empty folders).
• Maximum number of MP3 files and folders that can
be contained in a disc: 300.
When a file/folder name contains many characters,
this number may become less than 300.
• Maximum number of trees that can be played: 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).
