Help with manual

[Will Edwards]

Hi all:

I've been looking through the manual for the Debrie Parvo "L" camera. "434" in the diagram seems to be pointing to nothing. At least I can't tell what it's pointing to. Can anyone help with this?

I think it's the button at bottom right of the black square area on the crank side.
