Playable discs/filesDiscs CDs with one of the marks below on the surface.

Files Files in audio CD format, MP3/WMA files on a finalized CD-R or CD-RW. MP3/WMA files in a USB device can also be played.

•MP3/WMA discs require a longer readout time than regular CDs. (It depends on the complexity of the folder/file configuration.)

•Some MP3/WMA files cannot be played back and will be skipped. This results from their recording processes and conditions.

•When making MP3/WMA discs, use ISO 9660 Level 1 for the disc format.

•This unit can play back MP3/WMA files with the extension code <.mp3> or <.wma> (regardless of the letter case upper/lower).

•It is recommended that you make each MP3 file at a sampling rate of 44.1 kHz and at a bit rate of 128 kbps. Similarly each WMA file at a sampling rate of 44.1 kHz and at a bit rate of 96 kbps.

•Playback order of MP3/ WMA files may be different from the one you have intended when recording. If a folder does not contain MP3/ WMA files, it is ignored.

•This unit cannot play “packet write” discs.

•If a CD-RW has been recorded in a different format, erase all data on the CD-RW completely before recording on it.

•This unit can recognize up to a total of 511 tracks and folders on a disc, and 65536 files in up to 200 groups (maximum 500 files in a single group) on a USB device.

•The reflection factor of CD-RW is lower than that of other CDs, possibly causing CD-RW to take longer time to read.

•In this manual, “file” and “track” are interchangeably used for MP3/WMA operations.
