Patent ID: 7885615

Claim:
A method for operating a wireless communication device comprising a microprocessor, a push-to-talk button coupled to the microprocessor, and a radio chip processor coupled to the microprocessor and being switchable between an on push-to-talk state and an off push-to-talk state, the method comprising: using the microprocessor to check a status of the push-to-talk button relative to a status of the radio chip processor, and if the push-to-talk button is on and the radio chip processor is in the off push-to-talk state, sending a command to switch the radio chip processor to the on push-to-talk state, if the push-to-talk button is off and the radio chip processor is in the on push-to-talk state, sending a command to switch the radio chip processor to the off push-to-talk state, if the push-to-talk button is off and the radio chip processor is in the off push-to-talk state, remaining in this off state, and if the push-to-talk button is on and the radio chip processor is in the on push-to-talk state, remaining in this on state.
