On the viking website there is a help number:

I had a designer 1 and used the old style mega hoop where I had to advance and change positions to go to the next portion of the design. I no longer have the machine nor the hoop. I did find the section on the viking site where you can download manuals for older machines but the #1+ , machine was not listed. And it doesn't look like the old style mega hoop is listed anymore. Maybe if you call the help number?
