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.
