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.
