Abstract
A technique substantially reduces power consumption of a selective call radio (106) while the selective call radio (106) is in an inactivated state. During the inactivated state a power state of the selective call radio (106) is cycled at an inactivated duty cycle and a first selective call message having a selective call address of the selective call radio (106) is received and processed. An activation mode of the selective call radio (106) is set to an activated state during which the power state of the selective call radio (106) is cycled at an activated duty cycle. The activated duty cycle is substantially greater than the inactivated duty cycle. The activation mode of the selective call radio is set to the activated state in response to an activation command generated during the inactivated state.
