Are the Collars which are present at the start of a session just reminders, as hey are Glass ones, to prevent an alternative option being selected in error or are these routes no longer allowed?

While I suspect the former as they aren't Red it would be good to get confirmation.

The glass collars shall prevent pushing a wrong button by accident. You can remove them at any time or only if you need to press the protected button.

Thanks, that's what I suspected.
