Gossen's also provide a good range of user guides for their older meters on their own site, under the collectors section - the Pro F being on of them. They were - two years ago at least - still servicing the Pro F (threw mine on a concrete floor - came back as good as new).

I just found this thread, and as it was of interest to me, I followed the link above. I just wanted to add that the Luna Pro's were marketed under different names outside the USA. The Luna Pro-SBC is listed on the Gossen site as the ProfiSix, and the Luna Pro-F is listed as the LunaSix-F.
