KX-TG6700BXB/KX-TGA670BXB

4.5.4.

Reset Circuit

Function:

This circuit is used to initialize the microcomputer when it incorporates an AC adaptor.

Circuit Operation:

When the AC Adaptor is inserted into the unit, then the voltage is shifted by IC331 and power is supplied to the DSP.
The set starts to operate when VCC goes up to 3.0 V or more in the circuit voltage diagram.

Note:

(*1) The initializing time of the DSP chip is 28 ms under normal conditions.
