I fell into a great opportunity and purchased a mint Alpha. Spent the afternoon at the lake getting familiar with it. Control panel is very straight forward to operate lights, aerators, etc., but I can't figure out what the button with the picture of a lock on it does. The button below it has an O2 symbol it.......don't know about that one either. Can someone shed some light on this plz??

Lock compartments?

That was my first guess too but upon further review I did not see any wires going to the latches.

The O2 one is for oxygen generator - there's a hockey puck looking thing in one of the livewells - once water covers it it will put out small air bubbles to help the oxygen level for the livewells. I have a 2013 and the button over the O2 button is a little gas pump to switch to an aux. fuel tank if it is equipped with one.

You got a great boat. I have the same rig.

Button with lock on it is for the auto locking feature of all compartments. Most boats didn't come with that feature unless the owner specified it. It was a rather expensive option but now I wish I would've done it. It locks all compartments and arms an alarm.

The O2 button is as described below. You cannot hear it run. You can look inside the livewell when it is full of water and see fizzing coming from the screen.
