Abstract

A user interface for a communication device includes a light emitting diode (LED) (200) providing both a transmit-carrier indicator and transmit-audio feedback to the user. By varying the intensity (202, 204, 206) and/or color spectrum (302, 304, 306) of the LED (200). relative to changes in transmitted audio, the user is provided with transmit-audio feedback. If LED (200) is a bi-color LED, then receive-audio feedback can also be indicated to the user by varying the second color's intensity and/or spectrum.
