PURPOSE:To reduce possibility of suffering interference during calling at the time of next call, by searching preferably a channel used in a previous call, and giving it prionty is the next call. CONSTITUTION:At the time of calling a handset 1, a talk switch 152 is switched to the contact T of a talk mode. Then, it is discriminated, the data of the channel used at the preceding call time is taken out from a RAM143, and is set at PLLs 113 and 124, and it is checked whether set up channel and down channel are used in other station by an NSQL signal. In such a case, the call as a matter of course has been performed with the channel without suffering the interference, and also, since the channel at this time is set at the one used at the time of a preceding call, the possibility that the channel is used by another station, especially, the cordless telephone of a single channel, is low. |
