Importance safety notice :
Components identified by mark have special
characteristics important for safety. Furthermore, special
parts which have purposes of fire-retardant (resistors), high-
quality sound (capacitors), low-noise (resistors), etc. are
used. Whenreplacing any of components, be sure to use
only 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 during
repair.
·
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.
