摘要： PURPOSE:To prevent a talking line from being in use continuously by detecting that a talking is finished and the charging is started and interrupting the ratio line based on the detected output. CONSTITUTION:If an end of talking switch 7 is left unoperated at the end of talking and a slave set 3 is connected to charging terminals 19A, 19B of a master set 2, a detection circuit 21 detects the start of charging. Then a control circuit 22 cuts the power of, e.g., a transmitter by using the detection output so as to interrupt the radio wave of a transmitter 10. While a receiver 5 of a radiotelephony set 3 detects the interruption of radio wave and a control circuit 23 interrupts the radio wave from the transmitter 6 by using the output, restores to the standby state thereby preventing the continuous transmission. In this case, the circuit detecting the interrupted radio wave of the receiver 5 is constituted by a conventional noise squelch or carrier squelch circuit.
