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。

Notes)
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.
