Panasonic CQ-R145U - Manual (Page 24)

I Troubleshooting
□ 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.
□ When Something Doesn’t Work
Check the charts below for possible causes and solutions to any problem you might be experiencing.
Some simple checks or minor adjustments may eliminate the problem.
□ Product Servicing
If the suggestions in the charts don’t solve the problem, we recommend that you take it to your nearest
authorized Panasonic Servicenter. The unit should be serviced only by a qualified technician.
□ Replacing the Fuse
Use fuses of the same specified rating (10 amps). 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 authorized Panasonic Servicenter for service.
