1. FEATUERS
- 32bit-times over sampling MASH 1bit 4-DAC system.
- Digital servo for reliable playback.
- PLL (Phase Locked Loop) synthesized tuning.
- 18-FM, 6-AM presets with preset scan
2. REPLACING THE FUSE
Use fuses of the same specified rating (15amps). 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.
3. 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.
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.
