PURPOSE:To eliminate the necessity of raising the voltage of a battery or a solar battery even when the control output voltage requires a voltage higher than the power source voltage of a radio equipment by connecting a battery in series or parallel according to the detection of a controlling signal. CONSTITUTION:When a receiving section 1 is not receiving a receiving signal, contacts 7-1, 7-2 or a relay 6 are at positions shown in the figure. Accordingly, batteries 3-1, 3-2 are connected in parallel and the power source is supplied to the receiving section 1, detecting section 2 and relay 6. Each battery is charged from a solar battery 4. When the controlling signal received by the receiving section 1 is detected by the detecting section 2, a contact of the relay 6 is switched, and the battery 3-2 is connected in series and voltage is supplied to an external control output terminal 8. Power source of the receiving section 1, detecting section 2 and relay 6 is supplied from the battery 3-1. Thus, it is not necessary to raise the voltage of the battery and solar battert even when the control output voltage requires a voltage higher than the power source voltage of the radio equipment. |
