What manual and what panel????
Good point. Since I first battled this years ago, not sure where I learned what I know! But to help, here is my indicator panel...
And in my quest to help my fellow RVers, I removed said panel and here is the backside...
If I remove the little circuit board, on the back side of it there are a couple of adjustment screws for the sensitivity on the holding tanks...
So after I felt I had both my holding tanks thoroughly flushed and empty, I used the adjustment screws to have them register empty - just a slight turn off of showing an indication of 1/3 a tank. Seems to be working for me.
Hope this helps.
