送受信機。It is equipped with a receiver and a transceiver configured to be able to switch between a receiving state and a transmitting state, and during standby, the transceiver is switched to a receiving state and set to a receivable state of frequency ft=f2, and frequency f1. If you set the transmitting state while not receiving f2, the transceiver will switch to the transmitting state and be set to transmit at frequency f2, and when it receives the signal of frequency f2 and enters the response state, the transceiver will switch to the transmitting state. 1. A transmitter-receiver characterized in that the transmitter-receiver is set to transmit at a frequency f1 when the frequency is switched to f1, and the transmitter-receiver is set to a transmitting disabled state when the frequencies f1 and f2 are received.
