Abstract
A radio selective calling receiver having a multiarea function includes a reception channel reception enable/disable information storage means. In a normal operation, only a specific frame is intermittently received using a predetermined first channel. When a 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 the specific frame is received using another channel other than the first channel, and reception enable/disable information for the another channel is stored. Immediately after the out-of-area state is detected, the 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.
