∙
Removable face plate security.
∙
Digital servo for reliable playback.
∙
PLL (Phase Locked Loop) synthesized tuning.
∙
18-FM, 6-AM presets with preset scan.
3 REPLACING THE FUSE
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
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
[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.
