NOTES
1. PC boards are shown viewed from foil side. :
2. The colors on the PC board illustrations have the following
significance:
CJ: GND
(7: other
3. Resistor values are in ohms (k=kilo-ohms M=megohms).
4. All capacitor values are in microfarads (p=picofarads).
5. A Parts marked with this sign are safety critical components.
They must always be replaced with identical components.
Refer to the appropriate parts list to ensure exact replacement.
