A synchronization controller identifies the timing of the group assigned to the receiver based on a synchronization signal detected by a preamble and synchronization signal detector. At this timing the power supply of a radio section is turned on. A selective calling number within the received group and pre-assigned selective calling number are compared in a selective calling number detector. The power supply of the radio section is immediately turned off, if the result of the comparison is non-coincidence. In this way, the battery saving efficiency can be enhanced by arranging to turn on the radio section only in the groups which are assigned to the receiver, and turning off immediately the power supply of the radio section when the receivers assigned selective calling number is not found in the receiver's assigned group. <IMAGE> |
