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 (5k-ohms/10W) 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（5kΩ /10W）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。
