  • Method and apparatus for power off control of a selective call radio
    Patent number: 5587706
    Abstract: A selective call radio (100) includes a receiver section (103), an address detector (210), a power off command detector (220), and a power control section (240). The receiver section (103) is for receiving and demodulating a radio signal. The address detector (210) is for comparing an address demodulated by the receiver section (103) to at least one selective call address stored in the selective call radio (100). The address detector (210) is also for generating an address detect signal when the address matches one of the at least one selective call address within predetermined parameters. The power off command detector (220) is for generating a power off signal when the address detect signal is generated and the radio signal includes a power off command. The power control section (240) is responsive to the power off signal for changing a state of the selective call radio (100) to an off state.
