Furthermore, special parts which have purposes of fire-retardant (resistors), high- quality sound (capacitors), low-n

18、oise (resistors), etc. are used. When replacing any of components, be sure to use only manufacturers specified parts shown in the parts list. Caution ! IC, LSI and VLSI are sensitive to static electricity. Secondary trouble can be prevented by taking care during repair. Cover the parts boxes made of

19、 plastics with aluminium foil. Put a conductive mat on the work table. Ground the soldering iron. Do not touch the pins of IC, LSI or VLSI with fingers directly. 17 Notes of Schematic Diagram 63 SA-PM33DBEB 64 SA-PM33DBEB 18 Schematic Diagram 18.1.
