Notes on Discs

If you use commercial CDs, they must have
either of these labels shown at right.
Some copy-protected music CDs are not
playable.
How to hold the disc
¡ Do not touch the underside of the disc.
¡ Do not scratch on the disc.
¡ Do not bend the disc.
¡ When not in use, keep disc in the case.
Do not use irregularly shaped discs.
Do not leave discs in the following places:
¡ In direct sunlight
¡ Near car heaters
¡ Dirty, dusty and damp areas
¡ On seats and dashboards
Disc cleaning
Use a dry, soft cloth to wipe from the center outward.
Do not attach any seals or labels to your discs.
Do not write on the disc label with a ballpoint
pen or other hard-point pens.
¡ You may have trouble playing back some CD-R/RW discs recorded on CD recorders (CD-R/RW drives), either due
to their recording characteristics or dirt, fingerprints, scratches, etc. on the disc surface.
¡ CD-R/RW discs are less resistant to high temperatures and high humidity than ordinary music CDs. Leaving them
inside a car for extended periods may damage and make playback impossible.
¡ Some CD-R/RWs can not be played back successfully thanks to incompatibility among writing software, a CD
recorder (CD-R/RW drive) and the discs.
This player cannot play the CD-R/RW discs if the session is not closed.
¡
¡ This player cannot play the CD-R/RW discs which contains other than CD-DA or MP3/WMA data.
¡ Be sure to observe the instructions of CD-R/RW disc for handling it.

Maintenance

Your product is designed and manufactured to ensure the minimum of maintenance. Use a soft cloth for
routine exterior cleaning. Never use benzine, thinner, or other solvents.
If the fuse blows out, consult your dealer, or your nearest authorized Panasonic Servicenter.
Warning
¡ Use fuses of the same specified rating (15 A). Using substitutes or fuses with higher ratings, or connecting the
unit directly without a fuse could cause fire or damage to the unit. If the replaced fuse fails, contact your
nearest authorized Panasonic Servicenter.
