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 positions 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, perform discharge
by connecting a discharge resistor (5k-ohms/10W)
between terminals at following positions.
The time required for discharging is about 30 seconds.
