Change Key Assignments on Sharp ER-A310
I've just bought a second hand ER-A310 The previous user had upgraded the machine to have the 30 Department Keys - unfortunately they removed all the key descriptions from this area - including the "AMT" key. I have read how to re-set the machine from "AskAnOwner", and also found the programming manaul for the A320 as recomended also on this site. However my register does not have an @/For key or an CA/AT key so I am at a loss how to even list what my keys are set to do. As you can see I am in a mess with this. I have a full user Instruction Manual for the ER-310 - and now also have the Programmers Manual, the Instalation Manual and the Service Manual for the 320 - but it does not help ! Please help, Thanks & Best Regards, Paul.
