Provides a group mode setting that can be set with a small number of operations, and matches the desired use scene, and the driver can easily use full-duplex and half-duplex communication devices with group registration functions separately. In the communication device having a group registration function, if the power supply SW and the registration SW are turned on at the same time (Yes in step S1), the operation proceeds to member ID registration (step S7). On the other hand, if the login SW is turned on after the power source SW is turned on (Yes in step S3), it proceeds to the operation of visitor ID registration (step S8). Therefore, the login of the group mode is simplified. When the above registration is completed, when the visitor call SW is disconnected, full-duplex communication is performed between the communication devices registered with the member ID, and when the visitor call SW is connected, half-duplex communication is performed for all slaves communication.
