With all due respect - that's what happens when you can not read the instruction manual (or not understood). The machine is now switched on and off by pressing certain keys electronically - so an innovative, electronic enhancement that makes the switch superfluous. The comment confused !!! It should be deleted because it prevents customers from buying that do not accurately can deal with it. At least I found it difficult to handle these failures comment until I present the original instructions. Have wasted a lot of time to it, and some phone calls.
