ABSTRACT:
A communication unit is improved to comprise a volume/mode selection switch, mode detector, volume level setting detector, and a processor. The mode detector and the volume level setting detector monitor the volume/mode selection switch to determine, respectively, the selected mode of operation and the volume level setting. The processor, which is operably coupled to the mode detector and the volume level setting detector, processes the mode of operation and the volume level setting based on the mode of operation selected.
