Furthermore, specialparts which have purposes of fire-retardant (resistors), high-quality sound (capacitors), low-noise (resistors), etc. areused. When replacing any of components, be sure to useonly manufacturer´s 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 duringrepair.· Cover the parts boxes made of 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.16 Schematic Diagram57SA-AK230PL
