Abstract
A system and method for aiding emergency service providers in locating an incapacitated individual by use of a wireless communications device. The invention has two major modes of operation based upon whether the line of communication between the handset and call destination is open or closed. If the connection between the handset and the call destination is open, the audible beacon periodically generates a preselected tone through the built-in speaker of the telephone. The audible beacon may be initiated from the call destination location, after there has been an established link between the telephone and the call destination, whether the connection is open or closed. Once the audible beacon is initiated, the stored volume settings of the handset are replaced by the volume settings of the audible beacon system and the preselected tone of a telephone ringer or a beep. The tone remains activated until manually turned off.
