File extensions

Always add a file extension “.MP3” or “.WMA” to MP3 or WMA file by using single byte letters. If you add a file extension other than specified or forget to add the file extension, the file cannot be played.

Logical format (File system)

1.When writing MP3/WMA file on a CD-R disc or CD-RW disc, please select “ISO9660 level 1, 2 or JOLIET or Romeo” as the writing software format. Normal play may not be possible if the disc is recorded on another format. such as packet write disc (UDF) format.

2.The folder name and file name can be dis- played as the title during MP3/WMA play but the title must be within 28 single byte alphabeti- cal letters and numerals (including an exten- sion).

3.Do not affix a name to a file inside a folder having the same name.

Folder structure

1.A disc with a folder having more than 8 hierar- chical levels will be impossible.

Number of files or folders

1.Up to 255 files can be recognized per folder. Up to 255 files can be played.

2.Up to a maximum of 255 folders can be sup- ported. However, actual folders support will still be depended on total files.

3.Tracks are played in the order that they were recorded onto a disc. (Tracks might not always be played in the order displayed on the PC.)

4.Some noise may occur depending on the type of encoder software used while recording.

CD-DA/MP3/WMA selection on multi-session CD

If a multi-session CD which contains CD-DA and MP3/WMA files is being inserted, user can select either CD-DA or MP3/WMA files to be played.

Notes:

CD-DA files will always be the first to be played while MP3/WMA files will be playing subsequent- ly.

The first folder is always CD-DA files (CD-extra or mixed CD).

If there is no MP3/WMA files in CD-extra/mixed CD, the unit may mute for a while and start to play from top (CD-DA files).

1.Press the [F-UP] button will move to the next folder and MP3/WMA files to be played.

2.Press the [F-DN] button will move to the previ- ous folder (if it is first folder) and CD-DA files to be played.
