An MCUof a multi-band receiver detects signal input levels from level detection circuitsand' of receiver circuitsand, respectively, and thereby determines and identifies to which frequency band a signal input has been performed or whether simultaneous signal inputs to frequency bands have been performed. The MCUcontrols over drive circuits for LEDsandaccording to the signal input statuses, thereby causing a multi-colored light-emitting indicatorto illuminate in different colors. Further, in a single signal input, the illumination color of the multi-colored light-emitting indicatorcan be changed within an identical color group according to the level of a received frequency, for display. Further, when the received frequency is the frequency stored in a memory channel, the illumination color can be made to be different from the colors emitted in the single signal input status.
