Abstract A method of activating a radiotelephone operable in a spread-spectrum multiple access radiotelephone system. A searcher receiver ( 114 ) is activated, and the searcher receiver ( 114 ) acquires a PN sequence timing of a pilot signal. At least one demodulation branch ( 122 ) is activated after activation of the searcher receiver ( 114 ), and the demodulation branch synchronizes to the PN sequence timing of the selected pilot signal after the searcher receiver ( 114 ) has acquired the PN sequence timing.
