None of the full page sets (with continuous backgrounds) will work because the screen size and number of buttons are different. But any of the free-floating icons will work.

Download the images you want by right-clicking and saving them. In the MX-980 Editor, find the page you want to add the icon, click on the button you want, and right-click to "Add LCD Button" (or push Insert). Select the gray box you just added and find "Image" section in the right-side panel. On Normal, click the arrow pointing down to import. Find the image you saved and open it.
