Erm, dyou want to take off the little panel in the pic or the whole lot from the bar.
If its just the switches :-
Take out the screw to the right, remove the mirror ( 6mm allen )
theres a small screw behind it, remove that.
There is also a small plastic plate across the bottom of the switchgear with a silver screw and a black screw in it, remove those and the plate also. the switches will then come off.
Not 100% if you need to remove the bottom plate as I mention above but, take it off anyway, it wont hurt.
Whats up, why the need to remove it?
