Abstract
A radio selective calling receiver includes a storage storing a plurality of frequencies each corresponding to a particular area in which a service is available. A synchronized frequency storage stores, frequency by frequency, the numbers of times of synchronization set up at consecutive sampling times together with the sampling times. When frequency search begins, a receipt frequency control sequentially searches the frequencies in accordance with the number of times of synchronization set up at a sampling time closest to the time at which the search has begun. The receiver is capable reducing a period of time necessary for a frequency search without forcing the user of the receiver to perform any special setting operation. This reduces the probability of missing a call meant for the receiver and saves power to be allocated to frequency search.
