ABSTRACT:
A dual address paging receiver is described having page memory for automatically storing a page in the mode addressed if the user does not reset the receiver within a prescribed time interval after an alert signal is started. After a page is stored it can be recalled in the mode addressed from page memory by operating the reset button.
The receiver provides two different kinds of alert signals depending upon the mode in which it is addressed. The receiver also provides a unique turn-on signal.
