A selective call receiver receives a selective call signal (400) comprising a preamble signal (410). The selective call receiver comprises receiver circuitry (102) for receiving and demodulating the selective call signal (400). A preamble detector (105) is coupled to the receiver circuitry (102) for detecting the preamble signal (410), and a battery saver circuit (126) selectively activates and deactivates the receiver circuitry (102) in response to a signal from a processor (114). The processor (114) provides the signal to the battery saver circuit (126) to deactivate and activate the receiver circuitry (102) during reception of the preamble signal (410) in response to and subsequent to the preamble detector (105) detecting a portion of the preamble signal (410). |
