From what I've seen and read about it doesn't have to be pointed in any specific direction. Once it's working you can look at the alignment in the app and it'll tell you if it's aligned or not. Has a box to show alignment. But it should work out of alignment or even tilted the wrong way. When I first turned mine on it was pointed 90º or so in wrong direction and about 45º tilted away from the satellite path.
It worked, downloaded update but speed was only about 25 mbps download. I aligned it and was over 100 mbps. So it should work but speed will be impacted.
