In contrast, when it is determined in step 429 that the confirmation key is not input, that is, when it is determined that a key indicating that the corresponding device control has failed is input, the remote controller performs the received device IR code set in step 439. It is checked whether all IR codeset information of the device has been extracted from the response message.

If it is determined in step 439 that all IR codeset information of the device has been extracted from the received device IR codeset response message, the remote controller notifies that the setting for the corresponding device has failed in step 441, and In step 435, the device configuration mode is exited.

On the other hand, when it is determined in step 439 that all the IR codeset information for the device has not been extracted from the received device IR codeset response message, the remote controller returns to step 421 and the received device IR code.
