2. Capacitor values are in microfarads (p=picofarads).
3. 

£

Parts marked with this sign are safety critical components.

They must always be replaced with identical components-refer 
to the appropriate parts list and ensure exact replacement.

注 意

1. 抵抗の単位はΩ（ｋ＝ｋΩ，Ｍ＝ＭΩ）です。
2. コンデンサの単位はμＦ（ｐ＝ｐＦ）です。
3.
