NNN-BC binding help

[El Chupacabra]

How do you mount/remove NNN-BC X-C ski bindings? I'm trying to take these bindings off some X-C skis that are going to the ski swap, and there seems to be a hidden screw under the toe end of the binding.

Here's what I've gotten off the ski:
- heel pad pieces (little serrated toothed things) - 1 screw per ski
- exposed screw near heel end of main binding piece - 1 per ski
- hidden screws underneath toe bumper - 2 per ski

I can rotate the main binding piece 360 on the ski, like there's a center-mounted screw still under the toe, but I can't figure out how to get to that screw.

These are Rottefella NNN-BC automatic bindings, FWIW.

HELP!

I just looked at my manuals to remember the deal. There is a third toe screw under the automatic button. I can't remember exactly how to take the button offf but I think that there is anotch on the side you can put a screw driver in and pop it off. Once off it's a normal posidrive screw.

Got it - thanks. The button cap pops off with a flathead screwdriver, allowing access to that last screw.
