ABSTRACT OF THE DISCLOSURE An MF (multi-frequency) signal transmitting control apparatus for use in a cordless telephone system is described. It comprises a fixed unit connected to an exchange and a portable unit connectable to the fixed unit by a radio channel. A dial signal is sent from the portable unit to the fixed unit, the dial signal including a dial signal discrimination code and a dial number code. An audio circuit forms an audio channel between the exchange and the portable unit. Circuitry is provided for detecting the dial signal to provide a detected dial signal discrimination and dial number codes. A control section is provided for keeping the audio circuit off for a first prescribed length of time after receiving the detected dial signal discrimination code and, after the lapse of the first prescribed length of time, sending from the fixed unit to the exchange an MF signal corresponding to the detected dial number code. The invention reduces the occurrence of erroneous detection of MF signals.
