Behavior of Electric Power Failure In case that the power from AC adaptor is lost and lose radio waves, BBIC (IC1) turns Q11 ON since handset presumes that base unit's power is falied. Base unit detects that power voltage of AC adaptor +5.5V is OFF, then turns Q351 ON. It's possible to use the units during the power failure, supplying power to VBAT of base unit from battery of handset through Q10, CHG terminal and Q351.
