<p>PROBLEM TO BE SOLVED: To provide a radiotelephone system capable of automatically switching a plurality of extension radio telephone sets for talking in a transceiver mode to the transceiver mode, and performing transmission by temporarily inhibiting transmission of the other extension radiotelephone set in the transceiver mode.SOLUTION: A transceiver mode start instruction signal is transmitted from a transceiver mode start instruction signal transmission part 104 of a telephone master device 1. In the case where the transceiver mode start instruction signal is received by a transceiver mode start instruction signal receiving part 202, in an extension radio telephone set 2, a transceiver mode start/stop part 208 starts the transceiver mode by changing a radio part 209 to a transceiver mode frequency in accordance with an instruction of a mode control part 203. The extension radio telephone set 2 that starts the transceiver mode transmits from a transmission inhibition signal transmission/reception part 215 a transmission inhibition signal that temporarily or usually inhibits transmission of the other extension radio telephone set 2-N through a predetermined operation upon a key input part 205.</p> |
