Rich auto b5x how to raise dust hood

Hi all, so I am slowly getting used to my new machine (a 10x7’ table, 8 tool linear atc, 4th axis and vac hold down using a rich auto B5x controller). I can’t seem to figure out for the life of me, how to raise the dust foot when I want to zero my z….. I have to jam my hand underneath it and blindly use a piece of paper, but it would be way less awkward and precise to raise the silly dust boot. Read through the manual a bunch of times and googled but still can’t seem to find what key command etc raises dust hood without doing a tool change.
