Abstract
An emergency-use-only cellular phone provides for contacting and establishing full duplex voice communication with emergency personnel at an emergency response center with the press of a single activation button. When the activation button is pressed a first time, the following functions are initiated: (1) electrical power from a power supply is provided to a cellular transmitter and receiver, (2) the cellular receiver is activated to search for an available channel from among A or B cellular system channels, (3) an emergency telephone number is accessed from memory, and (4) the cellular transmitter is activated to establish communication with the emergency response center. Since all of these functions are initiated by pressing a single activation button, communication with the emergency response center may be established simply and speedily, even under stressful conditions.
