PURPOSE: A mobile communication terminal using an ear-microphone attached with a memory button is provided to operate the memory button only of the ear-microphone without directly operating a keypad of the terminal, thereby transmitting a call signal with a telephone number designated by a user. CONSTITUTION: A controller(110) controls an entire operation. A display(120) consists of an LCD for displaying menu situations or state of a mobile communication terminal. A key input unit(130) outputs key data to the controller(110). A timer(140) checks whether various key buttons are pressed for a short or a long time. A storage(150) stores many telephone numbers in different addresses. A signal processor(160) transceives various data with a base station. A switch(170) checks whether an ear-microphone(200) is connected, and determines whether to input/output a voice to the ear-microphone(200) or a speaker and a microphone of the terminal. A jack connection sensor(180) checks whether the ear-microphone(200) is connected.
