Abstract
PURPOSE:To achieve the functions of interphone with the call out from the slave units even under radio reception, by providing the radio-interphone selector switch with the radio receiver to give the interphone functions to the radio receiver. CONSTITUTION:The radio-interphone selector switches S1-1 and S1-2 are provided between the circuit 1 and the amplifying circuit 4 and between the microphone in common use with the speaker 7 at the slave unit as the interphone and the call out signal generation circuit 4, in the radio reception circuit 1. Further, when the switches S1-1 and S1-2 are selected to the radio position at (a), the output of the circuit 1 is outputted to the speaker 6 via the amplifying circuit 3 and the transmission and reception selector switch S2-1. With this state, when the call out switch S4 provided with the slave unit is operated, the call out signal is fed to the circuit 4 as specified signal, and the specified call out signal is fed to the speaker 6 via the amplifying circuit 3 and the switch S2-1 with the circuit 4 operated, allowing to achieve the functions as interphone.
