"Radio Pager Having Local- and Wide--Area Reception Modes" ABSTRACT OF THE DISCLOSURE Disclosed is a radio pager wherein a manually controlled channel selector selects a first channel to operate the pager in a local area reception mode and selects a second channel to operate it in a wide area reception mode. A receiving circuit is responsive to the selector for receiving a first paging signal transmitted on the first channel and receiving a second paging signal transmitted on the second channel, the first and second paging signals containing address signals in first and second code formats, respectively. A decoder is responsive to the manual selector for comparing the address signal of the first paging signal with a first identification signal representing a user's identification number in the first code format and comparing the address signal of the second paging signal with a second identification signal representing the same user's identification number in the second code format. The decoder produces a coincidence signal when the address signal of each paging signal coincides with the identification signal of the corresponding code format to generate an audible tone.
