I am trying to change the price to all departments of the sampro er-060l following the manual, but the S1 or S2 key appears to be able to change it, and despite the million combinations I have made, there has been no way to do it. I have done it from the DEPT zone and I have also tried it from the numbers zone. The key is always in programming.
If anyone can help me .....

Thank you very much!!
