Normally, FMC drives the speed reference bugs on PFD and N1 reference bugs on EIS. If there is a fault with FMC or something similar, you can use these knobs to move the bugs yourself. Usage is rather simple - rotate outer part to indicate what you want to change (V1, Vr, Vref..., N1 on engine 1,2 or both), rotate inner part to change it.
