@Professor Chaos posted:The "Set" button should be under the little plastic cover at the bottom of the CAB-1. Slide it down to reveal the Set and momentum buttons.
It's often befuddled me why they put a cover over those buttons. They came to their senses with the Legacy CAB2, but retained it for the CAB1L. First thing I do is remove those covers and stash them in one of my parts boxes!
