Diki, there is a manual release, if the motor fails you can adjust it without the motor. If worse comes to worse you can leave it in the down position. From my recollection( of a former owner of the G70) the angle of the Pa2xPro in the down position is the same as the G70.
It is a gimmick, don't understand why they devoted the man hours to it either???
