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 k Ω /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。
