It's the equivalent of an infinitely variable gearbox. On the ground and during take off, the pitch lever is fully fine. Use throttle just like any fixed pitch a/c. On climb out at 300/500', throttle back to 25", pitch lever back to 2500rpm. In the cruise 23"/2300 rpm is a typical setting. To climb, increase pitch first, power second. To descend, reduce power first, if required increase pitch second. Usually, leave pitch alone, adjust power with throttle. Downwind, or on final when you get smart, pitch first - to fully fine, then adjust power second with throttle as before. You must have pitch fully fine for the go-around.
Clear as mud? Ask me if not happy.
Numbers for A2 not to hand, sorry but they're all in the POH.
