摘要： PROBLEM TO BE SOLVED: To obtain a radio communication terminal, which has a long operable time of a battery capacity by monitoring the battery capacity and switching to a 1st operation mode that reduces power consumption of a battery, when the battery capacity becomes a 1st reference value or less. SOLUTION: A controlling part 11 inputs a voltage signal of a battery 10 from a battery capacity monitoring part 9, which always monitors a capacity of the battery 10 and compares the voltage signal with a 1st reference voltage. When the voltage signal is the 1st reference voltage or less, it makes a call out to a center device and notifies a telegraphic message to the effect that the battery capacity drops. After that, it switches to such a power saving mode (1st operation mode) as to reduce the power consumption of the battery 10. For instance, a power supply changeover switch 20 is controlled in a fixed cycle (prescribed interval) by start from a clock 21, and the supply/stop of a power source to a sending and receiving part 18 and a TDMA processing part 25 is controlled. Then, it is possible to obtain a radio communication terminal, which has long operable time of the battery capacity.

摘要： PROBLEM TO BE SOLVED: To prolong the service life of a battery in a radio meter-reading device such as a PHS(R) terminal. SOLUTION: A required current consumption is made different for each of operating modes such as sleep mode, standby mode and meter-reading data transmitting mode of the PHS(R) terminal, this current consumption is detected by a CPU 6 as an output current 1 of a power unit 18 and corresponding to the detected output current 1, switches 7 and 4 are changed over. In the sleep mode or standby mode, the output current 1 is reduced and the first battery of small capacity of 3.6 V is used by turning on the switch 7. In the meter- reading data transmitting mode of great current consumption, the second battery of large capacity of 3 V is used by turning on the switch 4 and 3.6 V is always outputted by a switching regulator 5 regardless of the voltage drop of this battery. A voltage regulator 10 outputs the output voltage of 3 V at all the time. By selectively using batteries like this, the service life of the batteries is prolonged.
