Dori Dear, the way I wrote that may make it look more difficult than it will be for you. You already have a good understanding of diabetes, and know that the new AID System doesn’t remove all responsibility from you. Treat the re-read as a refresher - look at each topic and and ask yourself how you feel.
I don’t remember when your t-Slim was made but I’m thinking it is newer. If so, you will not need to unlearn and then learn the new menus and symbols.
