The back will do it automatically. It means that when shooting long exposures that you need to figure that each shot will take 2x as long, once for the original scene capture and then the same amount of time again while you patiently wait for your MFDB to do the dark frame and processing. Obviously when it's doing this you can't shoot another image until it has finished.
Some camera systems allow you to override this and not capture the dark frame and do noise reduction later in post processing. Phase backs, at least the ones I have, don't allow you to do this.
