A necessary index may be selected by selecting 'previous', 'confirmation', and 'next' through a key input of the user terminal 500 .

In this way, in response to the setting screen information in step S629, the first device 200 may receive specific identification information selected from a plurality of IR code identification information (ID) from the user terminal 500. Alternatively, the first device 200 may automatically select specific identification information, as shown, even if identification information is not selected from the user terminal 500 . That is, an order may be set in advance to first select 'IR #1', which is the first IR identification information, among the IR indices shown in FIG. 8 (S631).

The first device 200 transfers the selected IR code information to the remote control device 100 through step S631 and requests the remote control device 100 to transmit an IR test signal to the second device 300 (S633 ).

In response to the request signal, the remote control device 100 extracts an IR test signal corresponding to the IR code selected in step S633 from the IRDB and transmits the IR test signal to the second device 300 through IR communication (S635).

Thereafter, the remote control device 100 notifies the second device 300 that IR transmission has been performed by transferring the IR transmitted ID or index information to the first device 200 (S637).
