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 (

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.
