A slave unit 2 functions as a calling device which transmits a calling signal to a locator 3 provided to an item using a locator protocol. Completing one-to-one registration with the locator 3, the slave unit 2 transmits a piece of registration information to the master unit 1 via radio communication. Receiving a request from the slave unit 4 as an added calling device, the master unit 1 transmits the stored registration information received from the slave unit 2 to the slave unit 4.
