Hey Gogo. You're already doing great by being on this forum seeking advice. Just keep practicing and learning. Tin and Johns advice are great and your first couple pieces of info that will eventually help you learn your machine. Even though the MXT is a relatively simple machine for how powerful it is, there's still quite a bit to understand. No need to reinvent the wheel though, there's a lot of great people willing to share years of hard fought experience that will help speed up the learning curve tremendously. Best thing is every time you go out you will be able to understand more and apply that knowledge on your next hunt. You will love the MXT more and more every time you use it & in no time you will feel very comfortable with it. I would suggest picking up "The MXT Edge" by Jeff Foster as it's loaded with valuable info. The section on proper ground balancing and verifying audio stability (pp. 28-29 ) are worth the price of the book IMO. It' is simple, yet imperative, to learn this to be able to confidently maximize the machine for a given situation. Luckily the best way to learn what to dig, etc. is to practice, practice, practice and that's the fun part. Good luck.
