Abstract
A cordless telephone apparatus adapted to produce a ringer tone from a connection device during power stoppage. The ringer circuit is rendered inoperative when the connection device and cordless telephone are connected via a radio circuit in response to an incoming call from a subscriber's line, and rendered operative in at least one of the two cases in which the connection device and the cordless telephone are not connected via the radio circuit in response to an incoming call from the subscriber's line and in which the power source stops supplying power.
