3 REPLACING THE FUSE
TOP PREVIOUS NEXT
Use fuses of the same specified rating (15A). 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.

4 MAINTENANCE
TOP PREVIOUS NEXT
Use a dry, soft cloth to wipe. Never use solvents such as benzine, thinner as they may mar the surface of
the unit.

5 NOTES
TOP PREVIOUS NEXT
[RADIO BLOCK]
Do not align the AM/FM package block. When the package block is necessary, it will be supplied
already aligned at the factory.
[CD DECK BLOCK]
This model has no servo alignment points because microcomputer controls the servo circuit.
