Notes)
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.
