Abstract: A method for testing an assembled telephone (10) includes activating the telephone (10) and automatically transmitting a poll command from a processor (60) of the telephone on a bus (66) of the telephone (10). The method also includes receiving a test command from a testing device connected to the bus (66) in response to the poll command. The test command is operable to automatically initiate a test of the telephone (10). The method further includes automatically initiating a standard operational mode of the telephone (10) if the test command is not received by the processor (60) in response to the poll command.

Abstract: A housing (100) for a unidirectional microphone (102) is described which has an enclosure (104, 106) for holding the unidirectional microphone. The enclosure has a first plurality of apertures (108, 110, 114) for transmitting acoustic energy to the front and back of the unidirectional microphone. An assembly (116) is movably coupled to the enclosure which, in a first position, facilitates transmission of acoustic energy to both the front and the back of the unidirectional microphone via a first subset of the first plurality of apertures thereby facilitating unidirectional operation. In a second position the assembly inhibits transmission of acoustic energy to the back of the unidirectional microphone by blocking a second subset of the plurality of apertures thereby facilitating omnidirectional operation.
