· PLL (Phase Locked Loop) synthesized tuning.
· 18-FM, 6-AM presets with preset scan
· Digital servo for reliable CD playback.
· Removable face plate.
2 REPLACEING 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.
3 MAINTENANCE
Your products 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.
4 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.
