A radio selective calling receiver has a function of causing a reception section for receiving a transmitted radio signal to intermittently receive the radio signal by intermittently supplying a reception section power supply ON signal for turning on the reception section. The radio selective calling receiver detects the movement of the receiver out of a coverage zone on the basis of data indicating that the radio signal received by the reception section contains no sync signals having a predetermined period. The receiver then determines the state of movement out of the coverage zone on the basis of a received state of the sync signals within a predetermined period of time in the past until the movement of the receiver out of the coverage zone is detected, and controls the time intervals at which the reception section power supply ON signal is supplied to the reception section in accordance with the determined state. |
