NOTES:
1. Resistor values are in ohms (k=kilo-ohms, M=megohms).
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. £マークのある部品は安全規格重要部品です。
交換するときは必ずティアック指定の部品を
使用してください。
