Dirk means have you checked this?
4. Please notice the valve surface light change V1~V4. (in mode 2)
*(mode 2) The normal change light is as follows :
On power → V2-(Gear in) & V4-(Door close).
Press " MANU" button → V4 Jump V3-(Door open) → V2 Jump V1-(Gear out) → V3 Jump V4-(Door close)
I can assure you mine does not do that^^^^^
On power up V1 and V4 are illuminated. Another words, Gear DOWN door CLOSE...AT THE SAME TIME....
