What is the "Test Phrase" button on the VAC Buider suppose to do. Haven't been able to figure it out. I click the button and it turns green and all the other buttons turn gray (except "Exit"). After that nothing happens and I cannot make something happen. If I click the "Test Phrase" button again, it turn turns gray and the other buttons re-activate.
I guess I'm dense today, but I cannot find information on how to use the "Test Phrase" button.
Thanks,
