My 945 do not have the menu described here:

is my watch faulty or is there an error in the user manual?
I don't have it either. Maybe it's a precursor of a feature to be added by a software update, since the Power Manager is something that exists in other models (Fenix6 especially comes to mind) and is asked for by users of 945 as well?
