Abstract: A method and apparatus for operation of a remote speaker microphone over an expanded temperature range. By monitoring a temperature of the communication device, a temperature sensitive microprocessor can be disabled above a predetermined extreme temperature, thereby allowing control of an audio path of the communication device to be modified. Microphone and speaker signals of the communication device can be switched or rerouted to an electronic path capable of operating above the predetermined extreme temperature for expanded operation while previous microprocessor controlled digital and analog audio circuits are shut down.

Abstract: A communication system (100) formed of a portable radio (102) and radio accessory (106) is provided in which the accessory (106) provides emergency strobe and flashlight modes, the flashlight mode further providing a low battery indicator. Strategic control of lighting triggers and patterns allows for a single high intensity LED (132) to be used for both emergency strobe and flashlight modes, with minimized impact on battery life.
