Abstract
A radio communication device (10) comprises a radio transceiver (12), having a received signal strength indicator (RSSI) (16), an audio section (22), and a controller (16) for deactivating the audio section whenever the RSSI indicates the the received signal strength is below a predetermined threshold. The controller also operates as a counter (26) for indicating the length of time that the received signal strength has been below the predetermined threshold.
