2. REPLACEING THE FUSE
Use fuses of the same specifiedrating (15amps). Using different substitutes orfuses with
higherratings, orconnecting the unit directlywithout a fuse, couldcause fire ordamage tothe
unit.
3. MAINTENANCE
Yourproducts is designedand manufacturedtoensure the minimumof maintenance. Use a soft
clothforroutine exteriorcleaning. Neveruse benzine, thinnerorothersolvents.
4. RADIO ALIGNMENT
Donot align the AM/FM package block. Whenthe package block is necessary, it will be supplied
alreadyalignedat the factory.
5. CD DECK ALIGNMENT
This model has no servoalignment points because microcomputercontrols the servocircuit.
