It's the one I use but I don't have a manual but its easy enough to use. If you need any hel, I can possibly be of assistance.
PS, Sorry my model seems to be an earlier type with the three buttons on the front..
Assuming your Kombi B6 follows the earlier models in functions, it shouldn't be too difficult to work out by trial and error. There were basically 4 switches: a separate one for switching between 1 - 6 and 1-60 seconds; an off switch; a focusing (permanently on) switch; and a timed on switch depending on the seconds indicated by the timer.
