If you're lucky like me you'll get a Chinese manual instead of English...
How that happens, god knows, but I found the English version online and was good to go. This is coming from a guy who had no clue as to the first thing about radios. You just need to read through our manual. If you don't know something write it down and do a quick Google search later. After doing this a couple times you'll learn your basics. When you're on forums like this and read about a setting or feature that interests you, write that down as well so you can go to your manual later and look into it.
Once you get your license and you can actually use your radio for what it's made for, you'll learn a ton by just tinkering and using it. Don't worry about not understanding, this community has plenty of people out here to help you. Any questions need only to be asked and you will get probably more feedback than you could ever need.
