PURPOSE:To use a control channel at other equipment with a simple circuit constitution by changing and setting the frequency of the leaking transmitting electric wave of a master equipment or a terminal equipment to the frequency outside the band of a wireless channel when a queuing condition is obtained, in a cordless telephone set, etc. CONSTITUTION:When a queuing condition is obtained, for example, a control part 16 of a master equipment controls a synthesizer for transmitting, sets the transmitting frequency of respective transmitting parts 11 to a waiting channel and turns off the power source of an electric power amplifying part 12. Here, the waiting channel is the prescribed frequency outside the band of a wireless channel (composed of plural calling channels and one control channel) used at a said system. At a master equipment, when incoming is executed, the control part 16 controls a synthesizer for transmitting, makes the transmitting frequency of a transmitting part 11 from the waiting channel into a control channel, turns on the power source of the electric power amplifying part 12 and the sending of a calling signal from a transmitting antenna 14 is executed by the control channel. |
