No.
You are correct in leveling the mast. A bubble level on the top of the mast works well for getting the mast vertical.
You need to get the Azimuth, Elevation, and Skew values from either the DPP 1000 installation Manual or Dishpointer.com. Set the Skew on the dish before putting the disk on the vertical mast. Set the Elevation and aim the dish in the direction of the Azimuth. The arm of the dish does not point to the satellite. The actual direction of the satellite beam is above and to the right of the arm. The attachment brackets on the back of the dish are better sighting for direction. Also, be aware that if you get the compass too close to the metal dish, the Deviation of the compass reading will climb. At the dish, the compass may have to be from 9 to 19 degrees more depending where in the country you are. A quick tip is add 20 degrees and start your swing fof the Azimuth to the left.
With the mast vertical, the Elevation and Skew set , and the dish in the direction of the satellite, you should be picking up some signal. A good meter like the Acutrac III or the First Strike FS-1 comes in handy here to fine tune the dish without having to be seeing the TV, a big advantage when setting up in trees.
Swing the Azimuth for best signal strength and then tweak the Elevation. In 6 years on the road, I have never had to tweak the Skew.
I always run the Switch Check after setting up the dish because the compass Deviation can be enough to put you on the wrong satellite, typically 129. If you get 129, 119, x then you are too far to the right.
