miscellaneous button ser 6500ii

By programming one of the first 117 plu's as an open item, linked to a misc group and dept with a descriptor saying misc

Hi Andy,

Can you please explain it step by step how to do a misc many thanks x

what plu number do you want it to be? [where on keyboard?]
what group/department do you want it linking to?
without this info, cant be specific.
do you have the manual?
its easier to guide you through it on a page by page basis if you do.
if you have no programming experience whatsoever with these tills, it may require the assistance of an expert - where in the country are you?

I am in farnborough Hampshire yes I have the manual I want to use the button above the level 1 button x
