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。
・ C523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C523の端子間に接続して放電してください。
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 C523 is 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, perform discharge by connecting a discharge resistor (5 k-ohms/10 W) between C523 terminals.
