•
N
ote that the capacitors indicated below are dangerous even after the power is turned off because an electric charge remains and a high voltage continues to exist
there.
B
efore starting any repair work, connect a discharging resistor (
5
k-ohms/10 W) to the terminals of each capacitor indicated below to discharge electricity.
