Maintenance
Your product is designed and manufactured to ensure a minimum of maintenance. Use a dry, 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 authorized Panasonic service station. The product should be serviced only by a qualified technician.

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

≥ Press the reset switch if pressing any of the other
buttons has no effect.
