GN setting on an Olympus 35 DC

[Maase]

I recently got a hold of a lovely 35 DC and I have a question about the Guide number (GN) setting for flash photography.
I understand that when using 100 ASA film, I have to set the GN dial at 14, the guide number for my PS 100 G flash unit at 100 ASA. What do I do when using other film, e.g. 400 ASA? Do I leave the dial at the camera at GN 14 and simply change the film speed setting to 400? Or do I have to change the GN dial as well, to 28 (the GN at 400 ASA)?

So, in other words, does the camera automatically recalculate the GN when I change the ASA setting and am I consequenly supposed to set the GN dial just once: to the GN at 100 ASA?

Thanks for your advice!

Thanks, but exactly this is (in my opininion) NOT clearly explained in the manual...

Masse,

Try the link below. Although this references a 35RC, a full explanation of GN numbers, including settings for 400 asa, is included about half way down the page.
