I never been disappointed in my dealings with owners-manuals.com

Excellent printing quality. A complete and very useful manual with all details.

Even if the PDF is a scan, I can read the information I need.
The price is affordable and the service (mail sending) is very fast.

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.
