Yamaha YSP-2200 auto setup questions

Hi guys, i picked up one of these bars at the weekend but have a few questions about the auto setup.
How good is it to start with. I used it the first time and then had a look at the results in the menu. The sound levels were all over the place when doing the sound check and it had put the bar on a straight wall when it is actually in a corner.
Looking into the menus for adjustment quickly tells me i need some proper advice tho before messing it totally up.
Any help much appreciated.

Phil.
