A portable communication device includes a status indictor in the form of a single multicolor generating LED. The single LED indicates radio channel and battery status. The LED is responsive to a menu button press to indicate a current channel by color. Channel change is indicated by changing to another color. The LED is also responsive to a power button on the portable communication device to generate predetermined colors associated with battery status. The use of a single LED eliminates the need for knobs or a display as part of the status indicator of the portable communication device.
