All ICs and many other semiconductors are susceptible to electrostatic discharges
(ESD). Careless handling during repair can reduce life drastically. When repairing,
make sure that
you are connected with the same potential as the mass of the set by a wristband with
resistance. Keep components and tools also at this same potential.
1. Never replace modules or other components while the unit is switched on.
2. When making settings, use plastic rather than metal tools. This will prevent
any short circuits and the danger of a circuit becoming unstable.
1.1.3
To prevent electrical shock, do not use this polarized ac plug with an extension cord,
receptacle, or the outlet unless the blades can be fully inserted to prevent blade
exposure.
To prevent electrical shock, match wide blade or plug to wide slot, fully insert.
1.1.4
When replacement parts are required, be sure to use replacement parts specified by the
manufacturer or have the same characteristics as the original part. Unauthorized
substitutions may result in fire, electric shock, or other hazards.
1.1.5
Safety regulations require that after a repair the set must be returned in its original
condition. In particular attention should be paid to the following points.
