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。
