<p>A radio receiver (10) can be tuned selectably in a first mode to radio stations broadcasting in the 87.5 to 108.0 MHz FM2 band and in a second mode to event radio broadcasts on preset frequencies at least one of which is outside that band. A pair of push-buttons (20,22) can be operated to change the reception frequency to which the receiver is tuned. When the first mode is selected, the push-buttons can be used to tune the receiver to any desired frequency in the FM band and/or to the frequency of any desired signal being received in the FM band. When the second mode is selected, the push-buttons can be used to tune the receiver only to any one of the preset event radio frequencies. When the user wishes to change between listening to a broadcast in the FM band and listening to an event radio broadcast outside the first band, they therefore do not need to scan between the event radio frequency and the frequency of the other broadcast. Also, the user cannot tune the receiver to frequencies (which may be prohibited frequencies) between the event radio frequency and the FM2 band. The receiver is in a housing (12) that can be worn on the user's ear, and has a lanyard (118) that also forms an aerial and that is releasably connected to the housing (12).</p> |
