In A1200 its working but I mentioned working through user menu.
It seems out of three parameters of Tv type -> LongExp, ShrtExp and Ev Step, you can get only one parameter at a time in the user menu working. For others you will have to either use main menu or change the value parameter (EV Step value, Short Exp. Value, Long Exp. Value) in the main menu and then replace the old value with new value in the user menu. Its' not very user friendly. You have to decide which one you will use more often and keep that in the user menu.
