Operation time of a receiving section in a pager is reduced by interrupting the power supply to the receiving section upon reception of the signal having a transmission rate other than the pager self-transmission rate, or when only a noise signal is received. A timer section, counts the time elapsed since a control section started the power supply to the receiver section. A transmission rate detector section is operated when a predetermined time has elapsed. The power supply to the receiver section is interrupted when the transmission rate detector section judges that the transmission rate of the received signal is not a self-transmission rate, to reduce the power supply time of a battery.
