This was a perfect working machine we purchased from a business closing sale. They knew that the batteries went dead is all. We actually Googled ( CL511 Battery Replacement All About Circuits ) and they show that even when the batteries corrode, the circuit boards are rarely damaged.(last few pictures showing corroding batteries but the Boards look perfect). 16th picture shows the Introduction Info at the beginning of the Operators Manual. We have no cables with it, they should be easy to find or make. We are selling this at a low price cause it needs batteries and cables. We are not going to take returns on this because it needs the new batteries installed.
