Durst 1200 Pictochrom - Need HELP !!!

I just purchased a DURST 1200 Pictochrom CL Enlarger. The problem is: It just turn on to a low Light (Working Light?) but not to a strong beam. I do not have any manual. I may do something completly wrong - or the electronics in the control unit is brocken :-(

Is there anybody out, with a manual? How to spark the strong beam?

Thanks, all Help most welcome!

Marcus,
There are to buttons near (left) the exposure/start button. The right one (W.Light) is full light, with no filters in the beam, the left one (Light) is with filters and maybe set with a D=30 or D=60 Density filter. Check this by pressing "Time" and look at de display. If so, change it by pressing "0" and confirm with the button below the text "D.Filt" next press ËXIT" and try again.
