I was thinking I will never find this manual. User-Manuals had saved my Teac V-7010 which is full of specific functions. Superfast service, excellent document. Thank you very much!

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.
