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。
