I have the etowah valley boxes in my selfserve bays with the credit card readers and bill acceptors. I don't like the way the grace time works on this system. You can set up a grace time, but the meter doesn't display a grace time nor does it announce a grace time on the speaker. What good is a grace time if the customer doesn't know it exists? Am I missing something here? I have the grace time set up and it works, it just a waste if no one knows its there.
