Abstract: Portable communication device (100) generates a telephony audio stream and at least a second audio stream. Responsive to the occurrence of a telephony session, the second audio stream is re-routed from a loudspeaker (234) to a handset speaker (230) in the PCD (100) having a low capacity audio output capability. Upon termination of the telephony session, the second audio stream is re-routed from the handset speaker (230) to the loudspeaker (234). Subsequent to such re-routing, an audio output drive level of the second audio stream is caused to gradually increase over a period of time in accordance with a predetermined ramp function. A series of warning tones are reproduced to warn the user of the potential for high volume audio.

Abstract: Method for operating a portable communication device (PCD) (100) such as a land mobile radio (LMR) involves, when operating the PCD in a half-duplex mode, a first speaker (330) adjacent a first end of the PCD being selectively used to reproduce received audio. In this mode, a first microphone (324a) is used to acquire a transmitted audio input for the PCD, and a second microphone (325) is used to acquire audio information for a first noise cancellation process. Conversely, when operating the PCD in a full-duplex mode of communicating, the function of the first and second microphones are reversed so that the second microphone is used to acquire a transmitted audio input for the PCD, and the first microphone is used for a second noise cancellation process.

Abstract: Systems (100) and methods (400) for operating a hybrid communication device (106). The methods involve executing at least one boot program. Responsive to the boot program, a first and second code are concurrently executed. The first code is operative for booting at least a real-time operating system on which a radio processor of the hybrid communication device is built. The second code is operative for booting at least a mobile operating system on which a cellular processor of the hybrid communication device is built. The radio processor provides support for wireless radio communication while the mobile operating system is booting.

Abstract: A remote control panel (RCP) is provided for controlling an operation of a radio (104, 106). The RCP (102) includes a keypad (208) configured for receiving user input commands for controlling the radio using the same keypad commands as would be used when operating the same without the RCP. The RCP also includes a display unit (206) for displaying information concerning an operational state of the radio. The RCP further includes a communication interface (212, 312-316, 320-322) configured for relaying information from the RCP to the radio located a distance away. The interface is also configured for relaying information from the radio to the RCP. The RCP includes a computer processing device configured for providing an extended capability for the radio exclusive of a predefined functional capability. The extended capability is selected from the group consisting of additional digital data processing capability, additional display capability, and additional communication capability.
