A transmitter (135) responds to a first control signal by outputting a transmit signal at a transmit power according to the first control signal. A power-level detector (149) responds to the transmit power by outputting a second control signal representative of a power level of the transmit power. A sensing network (159) is capable of changing from one state to another state in response to a stimulus, for example, the position of a retractable antenna (101) or attachment of a connector (113) or both. The sensing network may modify the second control signal depending upon the state of the sensing circuit. A controller (161) responds to the second control signal, whether modified or not, by determining the first control signal according to the second control signal.
