SPECIAL NOTE

Button designs on your remote may differ slightly from the example shown.
If the indoor unit is not equipped with a particular function, but your remote controller has a button for it, pressing that function’s button on the remote control will have no effect. When there are differences between the “Remote Controller Manual” and the “USER’S MANUAL” when it comes to function description, the description of “USER’S MANUAL” should take precedence.
