Safety measures
• Some internal parts in this product contain high voltages and are dangerous. Be sure to take
safety measures during servicing, such as wearing insulating gloves.
• Note 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.
Before starting any repair work, connect a discharging resistor (5 k-ohms/10 W) to the terminals
of each capacitor indicated below to discharge electricity.
The time required for discharging is about 30 seconds per each.
