The controller 111 checks whether a telephone number is input in step 212 when the key input unit 113 enters the memory mode according to a user's request. When the phone number is input, in step 213, the control unit 111 controls the display unit 114 to display the authorized phone number. When the function key for the English letter input mode is applied in step 214, the control unit 111 displays the English letter applied in step 215. In this case, the key input unit 113 includes an English letter in the numeric key. Thus, when the user enters the English alphabet input mode and presses a numeric key written in English letters, the controller 111 displays a corresponding English letter. When there are multiple English letters on one numeric key, the control unit 111 selects a desired English letter by using a change key.

In step 215, the English character of the called party desired by the user is displayed on the display unit 114, and in step 216, the control unit 111 checks that the storage key is input from the key input unit 113. When the storage key is input in step 216, in step 217, the storage unit 111 temporarily stores the telephone number in the memory 112 together with the alphabet. Thereafter, when the memory address key is input by the user in step 218, the control unit 111 searches for an English phone number table provided in the memory 112 in step 219 and confirms that the phone number is already stored in the memory address. Thus, in step 219, when the memory address is already in use, the controller 111 displays an overwrite question about whether to overwrite the control unit 114 under the control of the controller 111. When the storage key is input at the user's judgment in step 221, step 221 is transferred to step 222. In addition, when the storage key is not input in step 221 and the memory address key is input using the numeric keys, the control unit 111 processes from step 218. On the other hand, if the corresponding memory address is not in use in step 219, step 219 transitions to step 222.

In step 222, the control unit 111 stores the English phone number in the English phone number table provided in the memory 112 at the memory address by the memory address key.

In the standby mode of step 311, when the control unit 111 enters the English letter input mode by the key input unit 113, the alphabet letter applied in step 313 is searched for the alphabetic phone number table of the memory 112. Thus, the control unit 111 reads out the corresponding telephone number stored in association with the alphabet and displays it on the display unit 114 in step 314. When the transmission key is input from the key input unit 113 in step 315, the control unit 111 dials the telephone number in step 316.

When the user wants to make a call using the memory mode, the user must remember the memory address where the called party's phone number is stored or the English name stored in the memory address, and the memory address, the English letter, The inconvenience of having to refer to a list of English phone numbers with phone numbers. In particular, because the phone number is resisted by the English letter, the user does not use the memory mode, and the user often presses the phone number by referring to the phone number book.
