Abstract

A radio paging system for transmitting address signals and messages, as well as information common to a plurality of receivers, and a receiver applicable to such a system. The radio paging system includes: an encoder which produces a first code, followed by a string of address codes each of which is followed by message codes, and a second code followed by a string of information codes, a transmitter for transmitting a string of codes produced by the encoder; and a receiver which upon detection of the first code produces an alert signal and displays the message codes when the address code agrees with an address code stored in memory, and which, upon detection of the second code, displays the information codes which follow.
