Alerting system with dual-address memory
First Claim
1. In an electrically-operated alerting device that is responsive to a received calling signal to initiate an input signal for an alert generator, which device also includes means for supplying electrical energy to the device, an alert generator for providing alternatively a signal indicating the application of said energy to said device or an alert signal to a user in response to said input signal, said alert generator comprising:
- alert signal output means;
means to apply to said alert generator an energizing signal resulting from the application of power to said device immediately on application of power;
means to apply said input signal to said alert generator;
means to set said alert generator alternatively in a first state for a prescribed time interval in which it can report during only that time interval an application of power to said device or in a second state in which it can report a received calling signal event, means responsive to said energizing signal when said alert generator is in said first state to drive said output means in a first mode which audibly indicates the application of power to said device; and
means responsive to said input signal when said generator is in said second state to drive said output means in a second mode audibly distinguishable from the first mode and which indicates a received calling signal.

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 alert generator is also operable in two different modes that are audibly distinguishable from each other for alternately indicating either power turn-on of the device or the receipt of a calling signal.
