It's a shame that the floor indicators do not work anymore although the call station button does still light up. If you want to see them working, click on this link of the video we took back in 2011: Previous Video from 2011. This video is a Requested retake from awhile back - sorry I couldn't remember exactly who had requested these retakes since it's been awhile from the time they requested them for whenever we got back up to Davidson to reflim them.
