Hi Kelli. You use the tables in the programming manual to get the characters to make up the text for your store details. There is a section on programming logo which shows you how to use these codes in program mode. It's not too hard but you do need the codes. If you need a programming manual, one of the users has the UX43 programming manual here:

If you copy and paste it into your browser, it will take you to the Uniwell manuals. Hope this helps
