Maintenance

Your product is designed and manufactured to ensure a minimum of maintenance. Use a soft cloth for routine
exterior cleaning. Never use benzine, thinner or other solvents.

Product Servicing

If the suggestions in the charts do not solve the problem, we recommend that you take it to your nearest au-
thorized Panasonic Servicenter. The product should be serviced only by a qualified technician.

Replacing the Fuse

Use fuses of the same specified rating (15 A). Using different substitutes or fuses with higher ratings, or con-
necting the unit directly without a fuse, could cause fire or damage to the stereo unit.
If the replacement fuse fails, contact your nearest Panasonic Servicenter for service.

Cleaning this Unit

Use a dry, soft cloth to wipe.

Caution on Cleaning

Care of the Unit

How to hold the disc

Do not touch the underside of the disc.

Do not scratch on the disc.

Do not bend disc.

When not in use, keep the disc in the case.

Do not use irregular shaped discs.

Do not leave discs on the following places:

Direct sunlight

Near car heaters

Dirty, dusty and damp areas

Seats and dashboards

Disc cleaning
Use a dry, soft cloth to wipe from the center outward.

Caution on new discs
A new disc may have rough edges on its inner and outer
perimeter. These may cause malfunction.
Remove the rough edges using a pencil, etc.

Do not attach any seals or labels to your discs.

Do not write on the disc label in a heavy pen or ball-
point pen stroke.

Do not play any ordinary music CDs with labels
other than this one.

Notes on CD-Rs/RWs

You may have trouble playing back some CD-R/RW discs recorded on CD recorders (CD-R/RW drives), ei-
ther 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 them and make playback impossible.

The unit may not successfully play back a CD-R/RW that was made by the combination of writing software, a
CD recorder (CD-R/RW drive) and a disc if they are incompatible one another.

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 data.

Be sure to observe the instructions of CD-R/RW disc for handling it.
