Make the 6 tiles at the side of the doors say 1830 at the top of the door

"I" goes to the 1st square above the door. "F" goes to the 2nd square above the door. "Backwards L" goes to the 2nd square above the door. "3" goes to the 3rd square above the door. "7" goes to the 4th square above the door. Finally the "L" goes to the 4th square above the door. See related link for screenshots.
