Hello, my name is Rusty. Although I haven't had direct experience with that particular keyboard, I see on page 74 that you can change the upper and lower drawbars. Just above the display, notice it says upper and lower? I suspect you would move the cursor to the right to lower, then make the change. Does this help? I'm willing to look deeper into it if needed, but it sounds like you've gotten the hang of the keyboard already. I wanted to point out those two things.
