Disc Notes
—Continued
Notes:
•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 lev-
els deep.
In this manual, MP3 files are referred to as
tracks
.
Handling Discs
•Never touch the underside of a disc. Always hold discs
by the edge, as shown.
•Never attach adhesive tape or sticky labels to discs.
Cleaning 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, because
they may damage the disc.
Storing Discs
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.
