Notes on this schematic diagram
1. Values are voltages measured with a circuit tester (internal resistance: 20 k /V)
at respective points of the circuits with the power switch turned on.
2. The circuit diagram printed in this service manual is just a standard. The circuitry
and circuit constants are subject to change for improvement without notice.
