Since the radio selective call operation is the same as the conventional one, only the voltage control operation will be described here. When the output voltage of the battery 22 or the booster circuit 21 becomes equal to or lower than the specified voltage, the voltage detection circuit 15 detects the detection voltage, and the result is stored in the voltage detection recognition storage unit 14. This information is transmitted to the notification control unit 8 and the display control unit 9, and the driving unit 16
7 and the LED 18 and on the screen of the display unit 19, a first alarm is issued to urge the user to replace the battery 22 because the voltage of the battery 22 has dropped. The information from the voltage detection recognition storage unit 14 is also stored in the timer control unit 13.
And the timer control unit 13 starts the timer 11. The timer 11 starts counting in accordance with a value previously input from the input unit 20 and set in the timekeeping period setting unit 12. When the count of the timer 11 reaches or elapses the period set in the clocking period setting unit 12, the fact is transmitted to the power consumption reduction control unit 10. The power consumption reduction control unit 10 activates the battery saving function unit 7 to stop the operations of the radio unit 2 and the demodulation unit 3 to execute the power consumption reduction operation, and also operates the notification control unit 8 and the display control unit 9 respectively. The second time, when activated, causes the drive unit 16 to issue an alarm using the speaker 17 and the LED 18 and the display unit 19 to stop the operation of the receiver to prevent battery leakage, prompting the user to immediately replace the battery. Display is performed. Further, the power consumption reduction control unit 10 controls the operations of the ID-ROM 4 and the RAM 5 to execute a power consumption reduction operation.
