Patent ID: 7844307

Claim:
A wireless handset comprising: a long range wireless transceiver for selectively providing an inbound communication and an outbound communication through a wireless telephone network; an audio playback module, operably coupled to the processing module, for selectively producing an audio output from a stored audio file; wherein the long range wireless transceiver and audio playback module are powered from a single battery; a battery monitor module for monitoring a remaining power of a battery and for asserting a control signal when the remaining power compares unfavorably to a reserve power threshold; and a processing module, operably coupled to the long range wireless transceiver and the battery monitor module, for allowing an outbound communication from the range wireless transceiver while powered from single battery to an allowed recipient when the control signal is asserted, for prohibiting the production of an audio output from a stored audio file when the control signal is asserted, and for prohibiting an outbound communication to a disallowed recipient when the control signal is asserted, wherein the prohibiting an outbound communication to a disallowed recipient is overridden one time with entry of a one time password.
