If you set V2 in the speed window prior to takeoff, selecting AP on at 400 feet would maintain V2 speed and reverts to a type of LVL CHG mode. It does not sequence the bug to flap retraction speed. Once at acceleration height and upon reached the new bugged speed, you would select LVL CHG to continue your next segment climb.
