-32bit-times oversampling MASH1bit4-DACsystem.
-Digital servofor reliableplayback.
-PLL (Phase LockedLoop)synthesizedtuning.
-18-FM, 6-AMpresets withpreset scan
2. REPLACINGTHE FUSE
Use fuses of the same specifiedrating (15A). Using different substitutes orfuses with higher
ratings, orconnecting the unitdirectlywithout a fuse, couldcause fire ordamage to the stereo
unit.
3. MAINTENANCE
Yourproducts is designedand manufacturedto ensure a minimum of maintenance. Use a soft
cloth forroutine exteriorcleaning. Neveruse benzine, thinnerorothersolvents.
4. NOTES
[RADIOBLOCK]
Donot align the AMand FMpackage blocks. Whenthe package block is necessary, itwill be
suppliedalreadyalignedatthe factory.
[CD DECK BLOCK]
This model has no servoalignment points because microcomputercontrols the servocircuit.
