Abstract (en)
[origin: WO9307598A1] A selective call receiver (100) capable of receiving an energy source (101) having a first supply voltage (506) generates a second supply voltage (507) from the energy source and a third supply voltage (508) from the second supply voltage. The second supply voltage (507) is used to power at least an information display (209), and the third supply voltage (508) is used to power at least one frequency determining element (204).
