Abstract: A method and apparatus for expanding control switch selectivity in a portable communication system is provided. A rotary control switch is remapped based on the presence of two or more switches in the system thereby increasing the number of user selectable switch features, such as user selectable radio channels. The remapping can occur automatically without the need for hardware changes. The improved user interface can extend channel range selection in a portable communication system having a portable radio and radio accessory.
