ABSTRACT:
A portable radio communication device (102) includes a housing (302), and a transmitter (906) and control circuitry (902) disposed in the housing (302). The housing (302) is configured to carry a first battery source (112) and to optionally simultaneously carry a second battery source (114). The control circuitry (902) configures the transmitter (906) to transmit in accordance with a first set of power levels when the second battery source (114) is available, and in accordance with a second set of power levels when the second battery source (114) is unavailable. The first set of power levels includes at least one power level greater than any of the second set of power levels.
