Abstract
An apparatus for controlling a transmitter-receiver which can transmit and receive an aural signal and a data signal. In the transmission mode, the control apparatus detects a data transmission instruction of the transmitter-receiver and changes to the mode in that the data signal is supplied to the transmission unit of the transmitter, thereby executing the data transmission. On the other hand, in the reception mode, the control apparatus discriminates that the signal received is the transmission data to the transmitter-receiver and reduces the output volume of the receiving unit, thereby allowing the transmitter-receiver to receive the reception signal as the data signal.
