The manual should be helpful. Maybe you have the wrong one. You should have this manual:

http://the-checkout-tech.com/manuals/cashregisters/Samsung_ER-420M_operating_programming_manual.html

Look at the section called "initial clear" first. if that doesn't work, you may have to RAM clear it (all clear)
