ABSTRACT:
A paging receiver for automatically dialing a stored telephone number can consider an area code. A received telephone number stored into a memory corresponding to a number of depressions of a read key is displayed when the read key is depressed, and an area code stored into the memory corresponding to the number of depressions of an area key is displayed when the area key is depressed. Then, when the area code and the telephone number are displayed, an unnecessary extension number, etc., is erased by using an editing key. Thereafter, the area code and the telephone number are converted into a DTMF signal when a dial key is depressed and the DTMF signal is applied to an electronic exchange through a telephone, thereby performing automatic dialing.
