SERVICE PRECAUTIONS /
サービス時の注意事項
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.
