ABSTRACT:
A method for testing a communication link between first and second components of a system, which components communicate via a selected one of a plurality of broadcast channels, the second component being powered by a self-contained power source, the method comprising: causing the first component to scan a plurality of the broadcast channels in sequence in a receiving mode during a scanning period and to broadcast a test signal over the selected channel during the scan; and maintaining the second component in an inactive state in which energy consumption is minimized and in which the second component is unresponsive to broadcast signals during a major part of the scanning period, placing the second component in an active state in which the second component can detect the test signal during a time when the test signal is being broadcast, and causing the second component to broadcast a response signal upon detection of the test signal.
