This manual is very helpful, correct shematic diagram, and good exploded view.Perfect!

Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.

RESET CIRCUIT
When batteries are set or an AC adapter is connected, the reset IC provides a low pulse to the CPU. The CPU then initializes its internal circuit. When the power switch is pressed, the CPU receives a low pulse of POWER signal. The CPU provides APO signal to the power supply circuit and raises RESET signal to +5 V to reset the DSP, the key controller and the gate array.
