•Some audio CDs use copy protection that doesn’t con- form to the official CD standard. Since these are non- standard discs, they may not play properly in the CD receiver.

•The CD receiver supports 8 cm and 12 cm discs.

•The CD receiver does not support disc types not listed.

•Don’t use discs with an unusual shape, such as those shown below, as you may damage the CD receiver.

•Don’t use discs that have residue from adhesive tape, rental discs with peeling labels, or discs with custom- made labels or stickers. Doing so may damage the CD receiver and you may not be able to remove the disc properly.

CD-R/RW Compatibility

•The CD receiver supports CD-R and CD-RW discs. However, some CD-R and CD-RW discs may not work properly for any of the following reasons: disc burner characteristics, disc characteristics, the disc is damaged or dirty. See the manual supplied with your disc burner for more information. Condensation or dirt on the optical pickup lens can also affect playback.

•Make sure to use discs that have been finalized.

Discs Made on Personal Computers

Discs made on personal computers, including those of a compatible format, may not work properly in the CD receiver because of incorrect settings in the disc burning software. Check the manuals supplied with your disc burning software for additional compatibility informa- tion.

MP3 Compatibility

•MP3 discs must be ISO 9660 Level 1 or Level 2, Romeo or Joliet compliant. Supported formats: Mode 1, Mode 2 XA Form 1.

•Folders can be up to eight levels deep.

•MP3 files must be MPEG-1/MPEG-2 Audio Layer 3 format with a sampling rate of between 8 kHz and

48 kHz and a bit-rate of between 8 kbps and 320 kbps (128 kbps recommended). Incompatible files cannot be played.

•Constant bit rate MP3 files are recommended, how- ever, variable bit-rate (VBR) MP3 files between

8 kbps and 320 kbps are supported. (Playing times may not display correctly.)

•MP3 files must have a “.mp3” or “.MP3” file name extension. MP3 files without the proper extension will not be recognized. To prevent noise and malfunction, do not use these extensions for other types of files.

•The CD receiver supports up to 499 MP3 files and folders. Files and folders in excess of this cannot be played. Note that if the file and folder structure is very complicated, the CD receiver may not be able to read or play all of the MP3 files on the disc.

•Disc, file, and folder names may contain up to 32 char- acters.

•The maximum time that can be displayed for a single file is 99 minutes and 59 seconds.

•The remaining time cannot be displayed when playing MP3 files.

•MP3 file and folder names (excluding the extension) are shown on the display.

•Multisession discs are supported, however, some mul- tisession discs may take a long time to load and some may not load at all. When burning CDs, we recom- mend that you use a single-session (disc-at-once), and select “Disc Close”.

•Normally, the music in the audio session of a CD Extra disc is played. However, you can set the CD receiver so that it plays any MP3 files in the data session of a CD-R/RW disc instead. If the data session contains no MP3 files, the audio session will be played regardless. See “Setting MP3 Preferences” on page 35 for more information.

•The Emphasis is not supported.
