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 leave discs in the following places:
• In direct sunlight
• Near car heaters
• Dirty, dusty and damp areas

<Correct>
<Wrong>
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, fi ngerprints, 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/Fuse

Your product is designed and manufactured to ensure the minimum of maintenance. Use a dry, 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 specifi ed rating (15 A). Using substitutes or fuses with higher ratings, or connecting
the unit directly without a fuse could cause fi re or damage to the unit. If the replaced fuse fails, contact
your nearest authorized Panasonic Servicenter.
