ABSTRACT:
A radio telephone apparatus comprises detecting means for detecting a predetermined signal sequence other than a signal sequence associated with address signaling or an incoming call indicator signal and means for indicating that a call is received in response to the detection of the predetermined signal sequence. A user of the apparatus may prestore identification numbers of parties from whom the user wishes to receive calls. Also, by means of a transmitted password and a comparison of the password upon receipt with a prestored password, incoming calls will be received.
