2Vals, I went to hitch up the 5er at the storage facility and with a full charge on both batteries, there was a blank display on the leveling panel. I was able to make the legs extend or retract in order to hitch. Also, the Lincpad would not activate the legs at all. I called the dealer and made an appointment to bring it in as several things need attention while still in warranty. They told me it could be a fuse or the control box mounted on the ceiling of the front storage are is probably dead. I traced down the fuse in the battery area on the side of the trailer and it was good. I had power at the control box and I could make each leg extend or retract, but still had no display on the panel. I finally found that the wires that go from the panel to the control box connector was not fully seated at the control box. Bingo! It was again working properly. It was not completely clicked into it's socket of the control box from the factory. After it was again plugged in, the tablet would control the legs. It also takes a while for the router to recognize the tablet. I hope this helps you or others!
