1. Safety Instructions for Repairs
3.3 Be careful when taking measurements in the high-voltage section
1.1 Safety regulations require that during a repair:

- Safety components, indicated by the symbol , should be
replaced by components identical to the original ones.
3.5 When making settings, use plastic rather than metal tools.
- When replacing the CRT, safety goggles must be worn.
This will prevent any short-circuit and the danger of a circuit becomes
unstable.
1.2 Safety regulations require also that after a repair:

- The cabinet should be checked for defects to avoid touching, by the
customer, of inner parts.
