- Importance safety notice:
Components identifed 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. When replacing
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.
