The S (set) indicator and all Component Select buttons light up when you press these buttons, and turn off when you release them. Notes on the "learned" signals of an airconditioner About seasonal adjustments If you change the settings of the air-conditioner for the season, you have to program the remote control signals of the new settings on the Commander. If the power-on/off operation does not work correctly The air-conditioner may not be turned on or off properly with the button of this Commander to which you have programmed its power-on/off signal. If the Commander can operate only "ON" with one button and "OFF" with another, while your air-conditioner's remote control can operate "ON/OFF" with a single button, program the signal on two buttons of the Commander as follows. 1 Clear the "learned" power-on/ off signal. (In the example on page 35, clear the "learned" signal from the SYSTEM CONTROL 2 button.) 2 Program the signal (transmitted from the power-on/off button of the air-conditioner's remote control) for the SYSTEM CONTROL 2 button again. 3 Program the signal from the same button of the remote control for another button (for example, the SYSTEM CONTROL 3 button). The two buttons of the Commander have been programmed with the power-on signal and the power-off signal of the air-conditioner respectively, so that you can operate the airconditioner with the Commander. 37
