Using the Dynavox for total communication!

I am lucky enough to work with a client who has a Dynavox communication system. If you've never seen one, here is the company's website as well as a video success story of someone who uses the device. Thanks to our outstanding Dynavox Sales rep and some well educated staff, we were able to figure out how to set up the controls in the system so that he could turn on his TV and locate his favorite channels. It was surprisingly easy to do. The difficult part is making sure it is functionally positioned correctly and making sure that it is something that is accessible. Now, my client just needs time to practice but we are excited at this new adventure! Any suggestions would be appreciated.
