ABSTRACT:
A paging receiver selectively operable in either a six tone battery saving mode or in a five tone non-battery saving mode. The receiver features a serial code plug for programming a programmable tone detector to be responsive to a specific paging receiver address comprising a predetermined combination of preamble and paging signals. The use of a serial code plug in place of the parallel code plug previously known and utilized in the industry allows a reduced complexity of the paging receiver and a corresponding size, weight and cost savings.
