Abstract:
1. A method performed by a multiple function handheld device that includes a wireless communication processing module, a digital audio processing module, and a control module, wherein the method comprises: receiving a radio frequency (RF) control signal; and in response to receiving the RF control signal, the control module causing the multiple function handheld device to operate in a first mode by: the control module leaving at least a portion of a digital audio functionality that is provided by the digital audio processing module in a state of operation specified by a user, wherein the state of operation may be enabled or disabled, and the control module disabling the wireless communication module from providing a wireless communication functionality, wherein the wireless communication functionality includes processing incoming communications; wherein the control module also causes the multiple function handheld device to operate in a second mode by disabling the digital audio functionality and enabling the wireless communication functionality; wherein the control module also causes the multiple function handheld device to operate in a third mode by enabling the digital audio functionality and the wireless communication functionality, wherein, in the third mode, the digital audio processing module is operably coupled to process digital audio to produce processed digital audio, and the wireless communication processing module is operably coupled to process wireless communications to produce processed voice communication, and wherein the processed digital audio is mixed with the processed voice communication to produce a mixed digital audio signal; and wherein the control module also causes the multiple function handheld device to operate in a fourth mode by disabling the digital audio functionality and the wireless communication functionality.
