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.

安全対策
・ この製品の内部には高電圧部分があり危険です。修理の際は、
絶縁性の手袋を使用するなどの安全対策を行ってください。
・ 下記のコンデンサには電源を OFF にした後も電荷が残り、高電
圧が維持されており危険です。修理作業前に放電用抵抗（5kΩ
/10W）を下記の各コンデンサの端子間に接続して放電してくだ
さい。放電所用時間は各々約 30 秒間です。
