3 REPLACEING THE FUSE

Use fuses of the same specified rating (15A). Using different
substitutes or fuses with higher ratings, or connecting the
product directly without a fuse, could cause fire or damage to
the stereo unit.

4 MAINTENANCE

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

5 NOTES

[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.
