Ezyone Controller Hard to Set?

There aren’t many control boxes I find difficult to program, but this one is definitely a challenge. I carry a manual for this one in my glovebox as I need it every time I encounter one.

I’m not sure what they were thinking when they designed it, but if you’re like me and need the manual then here’s the link. (Its from a third party rather than the original manufacturer so I’m not sure how long it will be operational.)
