A method for automatically dialing in a paging system comprising a memory for storing a self-address into a first area of said memory, a received telephone number into a second area of said memory and a plurality of area codes into a third area of said memory, wherein said received telephone number is stored into said second area if said received telephone number is coincident with said self-address and thereafter, the stored telephone number is selected, edited and transmitted by a user depressing first to fourth keys, wherein the telephone number is transmitted as a dual tone multi-frequency signal generated through a telephone transmitter, said method comprising the steps of:

  • selectively displaying the stored telephone number corresponding to a number of depressions of said first key on display means when said first key is depressed;

    if said displayed telephone number comprises an unwanted digit, moving a cursor displayed by said display means one digit by depressing a second key for a first period being less than a predetermined time and changing said displayed telephone number by deleting a displayed digit flagged by said cursor by depressing said second key for a second period being one of equal to and greater than said predetermined time;

    if the area code is not desired for transmitting, converting the displayed telephone number into a dual tone multi-frequency signal when said third key is depressed, and transmitting said dual tone multi-frequency signal to the telephone transmitter;

    if the area code is desired for transmitting, selectively displaying the area code, corresponding to a number of depressions of said fourth key, on said display means when said fourth key is depressed;
