Abstract
A portable telephone including a synthesized local oscillator using a voltage controlled oscillator in the receiver section and receiving its operation power from either built-in battery or an external power source. A first external voltage substantially equal to the output voltage of the built-in batteries and a second external voltage higher than the first voltage are used as the external power source voltage. The output voltage of the built-in battery and the second external voltage are supplied to the voltage controlled oscillator in response to the use of the built-in battery and the external power source, respectively.
