Hi Sylvia,
No, there is no sequence to the knobs. Each of the four lines is controlled by its own knob. Adjust each so its line insects the circle. When all 4 do, they will snap to the correct position aligned with the center dot.
BTW You must select your destination on the viewer to the right of the console and get it entered before centering the lines. Just seeing the image is not enough. After the desired destination is there, you must confirm it by pressing the button and see the red geometric pattern on the screen.
