A remote controller that has preset therein control signals of various formats/code systems in correspondence with different kinds of electronic equipment and of different manufacturers detects the control signal from another remote controller typically used with the electronic equipment, compares it with the preset data, selects a predetermined signal from the preset data and stores it in a memory for use in controlling the electronic equipment. Identifier codes may also be stored in the memory to save memory capacity. With only one input operation, all control signals in the same category, such as channel codes for a television, may be learned and stored in the memory in correspondence with the respective keys. Provision is made to determine whether the input control signal is in the form of a toggle code, thereby executing the learn function for control signals that include the toggle code.
