A slave radio station establishes communization with a master radio station by transmitting a signal intermittently, listening for a response, and saving power by deactivating its transmitter and receiver at other times. When the master radio station responds, the slave station may synchronize periods of receiver activation with a beacon signal transmitted periodically by the master station and may cease transmission of the intermittent signal.
