Abstract

PURPOSE: To prevent the recovery of malfunction by rapidly establishing a radio link by breaking a switch, provided to an out-of-control voice-band component detector, with the radio line established and connecting it in calling to bear the relation to the extraction of a control signal.
CONSTITUTION: To the input of master station of the radio telephone unit which uses a control signal in the voice band, receives and supplies the control signal to control signal demodulator 3, and controls the signal sequencer by the output of demodulator 3 to establish the radio circuit link, detector 2 for the voice band component except the control signal is provided which detects the voice-band component except the control signal. The output of detector 2 is not used as a component suppressing the output of demodulator 3 and the output of demodulator 3 is regarded as a control signal direct; in calling, the ouput of detector 2 is used as the component suppressing the output of demodulator and when the output of detector 2 is not detected after calling, the output signal of demodulator 2 is regarded as a control signal.
