Abstract
A communication system is provided with a group registration function, which is capable of setting a group mode with the reduced number of operation, and simply selecting one of full duplex communication and half duplex communication by a rider, as needed. When a power supply switch and a registration switch are turned on simultaneously, member ID registration is executed. When the power supply switch is turned on and then the registration switch is turned on, visitor ID registration is executed. Accordingly, the registration of a group mode can be simplified. After the registration is ended, at the time of turn-off of a visitor conversation switch, full duplex communication is performed among communication devices subjected to member ID registration, and at the time of turn-on of the visitor conversation switch, half duplex communication is performed between the master and all of the slaves.
