■ 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.

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。
