A selective calling receiver having a radio system therein receives a selective calling signal in a first BS (battery-saving) mode when the power switch is in a first state, and receives it in a second BS mode when the power switch is in a second state. According to the first BS mode, power is intermittently supplied to the radio system at all times, and the second BS mode is such that power is intermittently supplied to the radio system for a set time period at intervals so that the selective calling signal is received for the set time period only. The second BS mode is set by determining a reference time point and the set time period such that power is intermittently supplied to the radio system for the set time period with a center time point at the reference time point. |
