Radio pager with reduced power consumption
 A radio-paging receiver gives a signal responsive to the receipt of a predetermined sequence of tone signals. The sequence is identified by an identification number stored in and read out of a read-only memory (ROM), which is a high-power consumption circuit. The remainder of the radio-paging receiver is constructed from low-power consumption components. Other than the readout of the ROM, all other of the circuit operations are carried out by the circuits having low-power consumption components. The high-power drain read-only memory is operated only momentarily and then its output is stored in low-power consumption circuits, for future reference. This way, the high-power drain operations are restricted to extremely short periods, with no energy wasted in a waiting time.
