Components identified by
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.
