Abstract
A radio pager receives from a base station a paging signal consisting of an address code group and a message code group including musical note data. The receiver separates the received paging signal into the address code group and message code group. Further, the receiver separates the message code group into message data and musical note data by using a melody start symbol and a melody end symbol. Then, the receiver generates melody frequencies corresponding to the consecutive musical note data, modulates the melody frequencies to output a melody, and drives a speaker therewith.
