Sony CDX-MP30 Operating Instructions Manual page 8

Notes
• With formats other than ISO 9660 level 1, 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 (non-
finalized disc).
Cautions when playing a disc that is recorded in
Multi Session
• When the first track of the first session is audio
CD data:
Non-music data 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.)

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)
• Maximum file number: 300
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.)
