Buttons 1 or 6 when there's no menu up cycle you through the available pages in your "screen rotation". The factory default rotation does go through the EMS pages. If it doesn't on your D180, then you'll need to hold button 6 to get to the page setup menu, which lets you add page layouts to the button 1/6 rotation cycle. See the manuals for details on this step. Or give tech support a call at 425-402-0433 while you're at the unit and they can walk you through it.
