PART REPLACEMENT AND

ADJUSTMENT PROCEDURES

CAUTIONS BEFORE STARTING SERVICING

Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to take a proper grounding

treatment as required.

Many screws are used inside the unit. To prevent missing, dropping, etc. of the screws, always use a magnetized screw-

driver in servicing. Several kinds of screws are used and some of them need special cautions. That is, take care of the

tapping screws securing molded parts and fine pitch screws used to secure metal parts. If they are used improperly, the

screw holes will be easily damaged and the parts can not be fixed.
