I have not set up that radio but I can tell you that if you are new to this, you will find that there are virtually no instructions for anything. Actually, let me amend that. There are no step-by-step instructions that tell you what to do in what order. There is a lot of information out there but it's a bit like having a recipe that lists the ingredients, but not how to put them all together.
I am also new to this and have found it very frustrating. There is a lot of doing things you're told to do without really knowing why. Be prepared for that and work through it.
