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:
Folder (album) MP3 file (track)
Tree 1 (root) Tree 2 Tree 3 Tree 4 Tree 5
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).
