It's easy as you want it to be, most settings work in most normal situations including out of the box factory settings.
It is when you are not in normal settings where learning to tweak the thing can come in handy and help you notice more.
Stay away from SL speed for now, don't mess with the notch system unless you understand how it works and if you do
learn how to do a reset.
Resets can be your best friend to REALLY undo notches, acclimate better in a heavy EMI filled site or correct most any wonky behavior.
Find a tone selection you like and go.

I learned way more after all this.
You can look at it you want, lots of tips the newbie can use, or at least you can see how my mind works, anyway.
Ignore the advanced stuff for now...plenty of time to get into all that if you even want to, later.
More stuff about some settings and behavior observations I have made peppered throughout the forum and on others.

It does everything I ever ask of it and way more most of the time in some of the worst conditions possible.
You will see.
Have Fun!
