Remember I wrote that the bottom 6 programmable keys were magic? Use the right key to scroll forward through each of the parameters, left for back, and change as needed. The second key up on the left will cancel the parameter you're working on, should you make a mistake. The phone system is called REMOTE IPC IP. Eventually you'll scroll to where it asks if you want to save. It's been so long since I've used one I had to plug it in to see what options were offered!
