There is a useful app from Lippert called "MyLCI" and it is available for free from the app store or wherever you get your app stuff.
It has manuals and videos plus other support info on most of their products including leveling systems and slide-outs, among others.
The app appears to be just a user interface that makes calls to resources stored in the cloud, so it requires a good internet connection. Even then it will seem slow and requires patience but I have found it useful. It was recommended to me by a Jayco tech when I called about slides.
Good luck and DON'T break a leg.
