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.

Receiver device and receiving channel setting method

A pager comprises a receiving section for receiving message data, an LCD for displaying the message based on the message data, and a memory for storing the format No. contained in the format code specifying the display format of the message and the actually displayed display format in such a manner that they correspond to each other. When a format code is sensed from the received message data, a display format is read from the memory according to the format No. contained in the format code and develops the subsequence display data on the display format, thereby displaying it on the LCD.
