A paging receiver which includes a conventional receiver circuit for receiving a paging signal, having a page number that identifies the intended recipient, a memory for storing a unique page number which is assigned to that particular receiver and a decorder for comparing the page number included in the received paging signal with the page number which is stored in the memory. If the stored and received page numbers coincide, detection pulse is produced that starts a first and a second timer. The first timer produces a mode switch pulse following the lapse of a first predetermined period of time. The second timer which has a period longer than first period of time, generates an auto-reset pulse upon lapse of its period. The mode switch pulse and the auto-reset pulse are sent to an annunciation mode switch having an output for driving both a tactile annunciator and an audible annunciator. The detection pulse causes the annunciator mode switch to energize one of the tactile and audible annunciators. When the mode switch pulse is generated by the first timer, the annunciator mode switch will drive the other of the two annunciators and turn the first annunciator off. Finally, the auto-reset pulse will cause the annunciation mode switch to turn off the second annunciator. A manual reset switch also provides a reset pulse input to the annunciation mode switch when can stop the activation of either the tactile or audible annunciator at anytime.
