How to set the remote controller exclusively for particular indoor unit
After you turn the breaker ON, the first remote controller that sends the signal to the indoor unit will be regarded as the
remote controller for the indoor unit.
The indoor unit will only accept the signal from the remote controller that has been assigned to the indoor unit once they are
set. The setting will be cancelled if the breaker has turned off, or the power supply has shut down.
Please conduct the above setting once again after the power has restored.
NOTE : For modification, take out the batteries and press the OPERATE/ STOP (ON/ OFF) button 2 or 3 times at first.
After modification, put back the batteries then press the RESET button.
