Abstract of the Disclosure A multiple alert pager has: a radio receiver for receiving a carrier wave modulated with at least a paging signal and demodulating the carrier wave; a decoder for comparing a demodulated carrier wave with a self alert code and generating an alert signal when a coincidence between the demodulated carrier wave and the self alert code is found; a plurality of alert means for paging a user in response to the alert signal; and a reset switch for stopping the alert signal, wherein the decoder switches among the plurality of alert means upon a first operation of the reset switch. Specification Title of the Invention Multiple Alert Pager Background of the Invention The present invention relates to a pager and, more particularly, to a multiple alert pager for selectively generating alert signals by a plurality of alert means such as an audio alert means for generating an audible alert tone at a loudspeaker, a visual alert means for generating a visual alert signal to turn on an LED, and a vibration alert means for generating a vibration alert signal to drive a motor, and so on. In conventional pagers of this type, when a user is paged or called, he must set a switch at a desired position to determine whether audio and visual alert means are simultaneously operated or one of the audio and visual alert means is operated. In this multiple alert pager, the switch must have the number of contacts which corresponds to the number of combinations of the alert means, resulting in an increase in size of receiver. Summary of the Invention It is a principal object of the present invention to provide a pager having a plurality of alert modes without an increased number of contacts. It is another object of the present invention to provide a compact multiple alert pager with good - 1 -
