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。
・ 下記箇所には電源を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）
を下記箇所の端子間に接続して放電してください。放電所用時間は約30秒間です。

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 positions 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, perform discharge by connecting a discharge resistor (5k-ohms/
10W) between terminals at following positions. The time required for discharging is about 30 seconds.
