• The following ID3 tags are supported: versions 1.0/1.1 

and 2.2/2.3/2.4. Versions 2.5 and later are not sup-
ported. Normally, version 2.2/2.3/2.4 tags have prior-
ity and will be displayed.

• For ID3 version 2 tags, the tag information recognized 

will be those embedded in the beginning of the file. 
We recommend that you include only title, artist 
name, and album name information in ID3 tags. Com-
pressed, encrypted, and unsynchronized ID3 tags can-
not be displayed.

With CD-ROM, CD-R, and CD-RW discs that contain 
many files and folders and files other than MP3s, it may take 
a long time to read the disc. We recommend that you include 
only MP3 files on your discs, use about 20 folders, and limit 
folder nesting to three levels deep.

■ CD

CDs contain tracks.

■ MP3

MP3 discs contain MP3 files organized into folders.

• Never touch the underside of a disc. Always hold discs 

by the edge, as shown.

• Never attach adhesive tape or sticky labels to discs.

• For best results, keep your discs clean. Fingerprints 

and dust can affect the sound quality and should be 
removed as follows. Using a clean soft cloth, wipe 
from the center outwards, as shown. Never wipe in a 
circular direction.

• To remove stubborn dust or dirt, wipe the disc with a 

damp soft cloth, and then dry it with a dry cloth.

• Never use solvent-based cleaning fluids, such as thin-

ner or benzine, commercially available cleaners, or 
antistatic sprays intended for vinyl records, as they 
may damage the disc.

• Don’t store discs in places subject to direct sunlight or 

near heat sources.

• Don’t store discs in places subject to moisture or dust, 

such as in a bathroom or near a humidifier.

• Always store discs in their cases and vertically. Stack-

ing, or putting objects on unprotected discs may cause 
warping, scratches, or other damage.
