ABSTRACT:
A multifunctional telephone capable of memorizing alphabetical characters and telephone numbers includes digit and function keys and a multi-row display unit. The lower row of the display is capable of displaying three groups of letters, A-I, J-R and S-Z above digits 0-9 printed on the face of the telephone. By pressing a corresponding digit key, a letter may be displayed on the upper row of the display. The upper row of the display is capable of showing a name while the lower row can display a telephone number. After the information has been entered into the telephone, it will be stored in memory. After pressing certain function keys, the telephone can search the memory for all information starting with a certain letter. This information will be sequentially displayed and may be automatically dialed after activation of certain other keys. Rather than displaying alphabet characters, "KATAKANA" characters or other symbols may be shown. Also, other information may be input and stored by the multifunctional telephone.
