PART REPLACEMEANT PROCEDURES
CAUTIONS BEFORE STARTING PART REPLACEMENT
Electronic parts are susceptible to static electricity and may easily damaged, so do not forget to ground as required.
Many screws are used inside the unit. To prevent the screws from missing or dropping, etc. always use a magnetized
screwdriver 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.
