ABSTRACT:
In a battery powered selective call receiver receiving a synchronous signal, a battery saving method extends battery life by optimizing the amount of time the receiver circuit is activated when searching for the signal after previously acquiring synchronization. The battery saving method allows for turning the selective call receiver on without activating the receiver circuit. The receiver circuit is activated at a time later than the energization of the selective call receiver, where the time of activation of the receiver circuit is determined in response to the time passed since synchronization was last acquired and the system signal stability.
