ABSTRACT:
In a cordless telephone system, a master unit adds to a registration signal an identification (ID) code assigned to a slave unit connectable to the master unit, a master unit transmission password, and an ID code assigned to the master unit, and sends the resulting registration signal to the slave unit. On receiving the registration signal, the slave unit determines whether or not the master unit transmission password is identical with a slave unit password stored therein. If the former is identical with the latter, the slave unit writes the master unit ID code therein, adds the master unit ID code, slave unit transmission password, and slave unit ID code to an end-of-registration signal, and then sends the signal to the master unit. On receiving the end-of-registration signal, the master unit writes the slave unit ID code included in the signal if the slave unit transmission password is identical with a password stored therein.
