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.
