How do i change a cashiers name on my Geller TOWA mp2?

I remember these registers fondly. I haven't got any notes on them any more so you will need a manual. I send my customers to C-tech as thats the only place I know of where you can download the programming manual. Hope this helps:

Don't worry about the different model number. It was re-branded for the UK by Geller
