•Close all windows and doors.
•Pull up the button for the window and hold it in this position for a few seconds.
•Let go of the button then pull it up again and hold it in this position. One-touch opening and
closing is now ready for operation.
The one-touch function can be restored for individual windows or for several windows at the same
time.

•Try to close the window again within a few seconds by holding the button. The roll-back
function will be deactivated for a small section of the path of the closing window.

reactivated. If it is still stiff or obstructed, the window will stop and will open itself automatically
again.
