A paging receiver having two warning modes, i.e., an audible mode and a vibrating mode, is provided. A vibrating motor of the paging receiver receives a voltage for controlling the level or intensity of vibrations provided by the motor. Various vibration voltage levels are provided to a multiplexer, and the multiplexer is controlled to sequentially output the various vibration voltages applied thereto, wherein each succeeding vibration voltage output by the multiplexer has a voltage level higher than a preceding vibration voltage.
