3. Parts marked with
A
(in the shaded area) are important as safety parts.
When replacing them, make sure to use the specified parts to ensure safety.
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.
