An apparatus for discontinuously operating a receiver (302) includes a receive data circuitry (304) and processor circuitry (306). The apparatus and receiver (302) are incorporated in a communication device (104). The receiver (302) receives a communication signal (106) having a plurality of frames (200, 214, 224). Each of the frames has a synchronization field (202, 217, 222) followed by a data field (204, 218, 228). The receive data circuitry (304) synchronizes the communication device (104) with the communication signal (106) received by the receiver (302) according to an initial synchronization field (202). The receive data circuitry (304) decodes the following data field (204). The processor (306) evaluates the decoded data field. If the decoded data field indicates that the receiver (302) is locked, the processor (306) powers off the receiver (302) for the following synchronization fields (222).
