Remote control unit, electronic device and method for controlling electronic device

An electronic device comprising:

• a key input part formed at an outer surface of the electronic device, for transmitting a control signal to a microcomputer of the electronic device depending on a key input of a user,
• wherein the key input part includes:
• a plurality of numeric keys providing different multi-digit numerals depending on input of the numeric keys, and
• a display part for displaying a multi-digit numeral depending on input of the numeric keys, wherein the multi-digit numeral displayed on the display part is determined differently according to a number of times that each of the numeric keys is pressed,
• wherein the multi-digit numeral is separated into two parts, a first one of the two parts corresponds to a menu item selected from among a plurality of menu items for controlling the electronic device, and a second one of the two parts corresponds to a control operation selected from among a plurality of control operations included in the selected menu items.

A method for controlling an electronic device, comprising:

• inputting a menu key formed on the electronic device or a remote control unit;
• allowing the electronic device to enter a setup mode depending on an input of the menu key;
• inputting a multi-digit numeral to a numeric key, wherein the multi-digit numeral is inputted to the numeric key of the electronic device or the remote control unit by pressing the numeric key a predetermined number of times;
• and
• inputting a confirm key of the electronic device or the remote control unit, and transmitting a control signal corresponding to the multi-digit numeral inputted to the numeric key to activate a setup of the electronic device,
• wherein the numeral inputted to the numeric key is determined differently according to a number of times that the numeric key is pressed,
• wherein the multi-digit numeral is separated into two parts, a first one of the two parts corresponds to a menu item selected from among a plurality of menu items for controlling the electronic device, and a second one of the two parts corresponds to a control operation selected from among a plurality of control operations included in the selected menu items.

A method for controlling an electronic device, comprising:

• displaying a predetermined multi-digit numeral by separately pressing a numeric key a predetermined number of times for each of the digits of the multi-digit numeral, the numeric key being provided in a key input part of the electronic device or a remote control unit;
• and
• transmitting a control signal representing a numeral depending on an input of a confirm key to achieve a control operation of the electronic device,
• wherein the displayed multi-digit numeral is determined differently according to a number of times that the numeric key is pressed,
• wherein the multi-digit numeral is separated into two parts, a first one of the two parts corresponds to a menu item selected from among a plurality of menu items for controlling the electronic device, and a second one of the two parts corresponds to a control operation selected from among a plurality of control operations included in the selected menu items.
