Double Locking
The double locking function prevents opening of a locked door from outside.
[Inside]
The double locking sound is generated
when the [Open/Close] button is
pressed, or the [Open] button of the
remote controller is pressed.
The double locking function is released when the indoor unit handle is
rotated downward, or the manual Open/Close lever is rotated to the
right or left.
Please be cautious when using this function, since the door can only be opened from
outside using the emergency key when the function is set. Please be particularly careful of
children accidentally setting this function from inside.
[Inside]
Press the [Open/Close] button for 2 seconds or
longer from the inside while the door is locked.
