How can I fix my treadmill?

So I'll turn my treadmill on, and it'll look like this:

The number "3" goes up to six, then it looks like this:

And that's usually what it looks like when I turn it on. So I'll try pressing a button but it won't work, and it'll just go back to P: 1, P: 2, P: 3, P: 4, P: 5, P: 6, that, ect. . .
I don't know what's going on. How do I fix this? I have a pro-form 380 CB
