Abstract:
A radio selective calling receiver having a multiarea function, which has battery saving means for, normally, intermittently receiving only a synchronization signal and a selective calling signal contained in a specific frame of a plurality of frames each having a synchronization signal and a selective calling signal and transmitted for every cycle, comprising:reception channel reception enable/disable information storage means,wherein, in a normal operation, only said specific frame is intermittently received using a predetermined first channel,when the synchronization signal is not received in a synchronization state wherein intermittent reception is being performed, the number of times of consecutive nonreception is counted,when the consecutive nonreception count has reached a predetermined value, it is determined that an out-of-area state is set, before the consecutive nonreception count reaches the predetermined value, the synchronization signal of another frame different from said specific frame is received using another channel other than said first channel, and reception enable/disable information for said another channel is stored, andimmediately after the out-of-area state is detected, said specific frame is received using a channel which is recognized, on the basis of the reception enable/disable information, as a channel capable of receiving the synchronization signal.
