programming esu switch pilot with bachmann dynamis

[acaet]

Hi everybody
I have a N gauge layout with 17 manualy SEEP operated  turnouts
Now I want to start work with switch point but I'm not able to program dynamis vs ESU switch pilot
I have the swp cursor in left position k83. Selecting accessories mode with left button bellow panel I have ACC001 01/1. I open menu to give a hotkey for the movement - key 6.
With the small black buttom on left top of SWP I open  it to program. The led starts flashing.
Clicking F6 buttom nothing happens. Clicking one of the turnout buttons the led stops flashing, remains light for some seconds and shuts.
Nothing remains programmed !
Both manuals Bachmann and ESU switch pilot are not very clear for this "job".
I'll apreciate some help
regards
