Mike, if you're not used to baitcasters, leave all 6 brakes in the on position. Later, you can take some out, to the off position by sliding them towards the center. It's best to disable them evenly around the spool so that on a 6 pin system you can either slide one pin on opposite side to each other towards the center or take half out by sliding every other one towards the center. Lots of variables there with the tension adjustment and different weight baits you'll be throwing.
Have a good time with it.
edited to add: Mike, I think the best guy on here to answer reel questions and baitcaster questions in particular, is Garry2r's. He knows his stuff and can give you very precise information. Maybe he'll see this and throw a post at you.
