The slave unit is equipped with a pilot signal generation circuit, the master unit is equipped with a pilot signal detection circuit that detects a pilot signal transmitted from the slave unit and closes a switch while the pilot signal is being detected. In a wireless telephone in which a base unit is connected in parallel with other telephones to one telephone line, and calls are made by operating the handset, the handset has a hold switch, and a hold operation signal is generated by operating the hold switch. a hold operation signal generation circuit that detects a standby signal and puts the handset into a standby state in which it only performs reception operations; a display element that turns off, a hold operation signal detection circuit that detects the hold operation signal in the base unit, and a hold operation that becomes activated by the detection output of the hold operation signal detection circuit and sends a hold voice signal to the telephone line. a voice signal generation circuit; and a telephone line voltage detection circuit that is activated by the detection output of the hold operation signal detection circuit and detects a drop in telephone line voltage due to a hook operation of the telephone;
1. A radio telephone comprising: a standby signal generation circuit which is activated by a detection output from the telephone line voltage detection circuit and generates the standby signal.
