Abstract
A radio pager of the present invention is capable of determining, during automatic area switching operation, a frequency having a high field strength by excluding the other frequencies having low field strengths. In addition, the pager is capable of determining such a frequency simply at low cost by use of its original antenna and radio frequency gain control function, i.e., without resorting to any additional circuitry.
