MULTIFUNCTION CONTROL INDICATOR FOR A VEHICULAR MOBILE RADIO

摘要

An improved user interface is provided for a front control panel (104) of a vehicular mobile radio (100) operating in a public safety environment. A multifunction control indicator is formed of a mode indicator light ring (126) co-located about a perimeter of a multifunction control knob (124). The multifunction control knob (124) controls two or more radio functions, such as volume and channel change. The mode indicator light ring (126) generates different lighting configurations in response to the multifunction control knob (124) being pressed to change radio functions. Numerous radio functions can be monitored and controlled via the multifunction control knob (124) and mode indicator light ring (126).
