Therefore, the manner in which the telephone is used when the base unit 30 and the handset 32 are not connected is the same as in the case of the cordless telephone shown in FIGS. 6 and 7. That is, since the connection detecting unit 104 of the base unit 30 does not output a detection signal to its detection output, the receive selector switch 100 and the transmit selector switch 102 are switched to the wireless receive terminal 100R and the wireless transmit terminal 102R, respectively. It has been switched. Similarly,
Also in the handset 32, since the connection detection unit 204 does not output a detection signal to its detection output, the receive changeover switch 200 and the send changeover switch 202 are set to the wireless receive terminal 200R and wireless transmit terminal 202R sides, respectively. has been switched to.
