PURPOSE:To ensure the reception by controlling the receiver so as to stop a call notice when a power voltage reaches a prescribed value thereby preventing stop of the operation of a control section. CONSTITUTION:When a low voltage detection signal 105 is inputted to an MPU 2 from a voltage detection section 28, interrupt processing is implemented by the MPU 2 and a low voltage alarm is outputted to a speaker 24 and an LED 25. Simultaneously, a low voltage signal is outputted to a display section 27. When an ID call exists after the detection of the low voltage, the notice by the speaker and a vibration motor is stopped based on an alarm from an IDROM inputted through an IDROM interface 8. Then a signal informing the presence of the reception is displayed only on the display section 27. In this case, a reception message is extracted from a storage section 2 as required and displayed on the display section 27. |
