Otis MRS pre-opening

Hi, guys (and gals, if any)
Anybody know how to disable pre-opening on an Otis MRS? (The "official way"!)

I know I could make my own circuit modifications to accomplish this, but I'd rather do it according to the OEM method to minimize liabilities.

..You,might try added another Dz sensor in the leveling head..putting them both in series..that would surely work..with a little dead zone adjustment..
