Well, I don't know if it has something to do with the CF, I don't have any. Moreover I couldn't find it in the manuals. :blink:

pull it "up" and then push it, the "plastic" card will come out.

for real cf cards, whcih have a high "hold" force, this is good

On the left looking at it from behind? That's to push the CF card out (like you sometimes have for some slots in laptops)

Hehe, thanks a lot! I didn't try to push it, I thought it was just a switch.
