Abstract
A receiver device, in which the receiving channel can be changed over to another, includes an RF unit which receives a plurality of channel frequency signals, a frequency conversion unit, an intermediate frequency amplifier and an FM detection unit, a signal intensity detection unit which, when the mode for setting the receiving channel is set, scans the channel frequencies to detect the signal intensities of the received signals in the respective channels and an A/D converter, a RAM which successively stores therein the signal intensities in the respective channels, and a CPU which sets the receiving channels on the basis of the signal intensities stored, detects the channel information contained in the received signals, and sets, when the detected channel information is the channel information of the desired channel, the channel of the channel information as the receiving channel for ordinary communications. Thus, the speed at which the change of the receiving channel and the registration process are established when the user is moving across service areas is enhanced to eliminate the feeling of uneasiness of the user and to shorten the length of time during which the user can receive no paging service.
