A paging receiver is provided for use with a plurality of paging service systems transmitting different radio frequency channels. The paging receiver searches for every reception channel and determines object reception channels by referring to system information identifying each service system, and comprises electric field detection means for detecting the electric field strength of radio frequency channels and reception channel control means for controlling searching for radio frequency channels and determining object reception channel. The reception control means immediately switches the radio frequency channel when the received electric field strength is not greater than a prescribed value and when the system information does not exhibit coincidence, but when the system information exhibit coincidence, determines that the radio frequency channel being received is an object radio frequency channel and continues receiving of the paging information. The time required for searching all radio frequency channels remarkably decreases thereby preventing degradation of the battery. <IMAGE> |
