2. Use designated parts only The sets components possess important safety characteristics, such as noncombustibility and the ability to tolerate large voltages. Be sure that replacement parts possess the same safety characteristics as the originals. Also remember that the A made which appears in circuit diagrams and parts lists, denotes components that have particularly important safety functions; be extra sure to use only the designated components.
3. Always follow the original design when mounting parts and routing wires The original layout includes various safety features, such as inclusion of insulating materials (tubes and tape) and the mounting of parts above the printer board. In addition internal Wiring has been routed and clamped so as to keep it away fiom hot or high-voltage parts. When mounting parts or routing wires, therefore, be sure to duplicate the original layout.
