Joel, it's never been out of the box. He's been recently (long time ago, waiting...waiting...) "evaluated" by an SLP and had the op to try the latest Dynavox technology and hated it. He's waiting for EZ Keys, that uses a push button switch and laptop.
So, I feel guilty having this in our closet if someone could use it. If no one on the forum answers in due time, I will give it to a local charity.
Thanks for the link, I forwarded it to hubby!
