Sharp ER-A570 reprogramming?
Hi Mark
My cash register above is proving to be very difficult to reprogramme. I have printed off the PLU but there is nothing on the report against each PLU $ or items. I tried to programm as per your instructions - P2 1210.x etc and which didn't do anything. When I pushed TL to finialise, nothing happened and I had to use CL to try again. Now when I switch back to Register mode every button pushed says not assigned. What has gone wrong.
