<p>PURPOSE: A mobile communication terminal and an operation method thereof operated by an input device capable of transmitting input signal from a user are provided to operate a mouse, a character input device or a signal transmitting device according to a setting operation mode of the user. CONSTITUTION: A key pad unit(107) generates a key signal corresponding to the selected key of character input keys and a menu key. The character includes a number. A key signal combining unit(111) produces a first character string by the combination of the generated key signal. A signal transceiving unit(117) transmits the generated first character strings to an external device. The signal transceiving unit receives the second character string. A second character string is retransmitted from the external device. A signal verification unit compares the coincidence of the second character string and the first character string.</p> |
