You need to program your new PLUs first, so set a name and price etc for the new PLUs before you do list programming.
When you have the list open so that you can see the PLUs associated with the list key (where you would modify a list PLU), move to an unused number and press YES.
Choose 'PLU' out of the two options.
Now you will see a list of all the PLUs in the machine. scroll down to the ones you have newly programmed and press YES for each one to add it.
Once you have added the new PLUs, press ESC
When it asks if you want to use the list key, choose YES and press the location for the list key. It will already exist there, so choose OVERWRITE
I hope that helps. this is a complicated feature that is normally set up by the dealer before you receive the machine.
Let me know if you have any trouble.
