Fine-Tuning the LNBF Setting

This adjustment is not needed for models with circular polarity.

Rotate the LNBF in a clockwise direction in very small increments. Each time
you move the dish wait five seconds while your assistant checks the Signal
reading. Determine where the signal begins to weaken and mark the location.

Rotate the LNBF in a counterclockwise direction in very small increments.
Wait five seconds while your assistant checks the Signal reading. Determine
where the signal begins to weaken and mark the location.

The optimum position is midway between the two points you marked in the
previous steps. This position should provide the strongest Signal reading.

Then move the LNBF in and out. There is a small adjustment range (1-1/2" or
4 cm) to find the best Signal reading for the LNBF.

Tighten the LNBF clamp screw(s) so that the LNBF cannot move.

Fine-Tuning the Elevation Setting

Raise the position of the satellite dish in very small, 1 mm (1

32") increments.

Each time you move the dish, wait five seconds while your assistant checks the
Signal reading on the Installation Settings menu. Mark the location where the
signal begins to weaken.

Lower the position of the satellite dish in very small, 1mm (1

32") increments.

Each time you move the dish, wait five seconds while your assistant checks the
Signal reading on the Installation Settings menu. Mark the location where the
signal begins to weaken.

The optimum elevation position is midway between the two points you marked
in the previous steps. This position should provide the strongest Signal
reading.

Tighten the nut(s) on the mounting bracket so that it cannot move up or down.

Fine-Tuning the Compass Direction Setting

First, turn the satellite dish clockwise in very small, 1 mm (1

32") increments.

Each time you turn the dish, wait while your assistant checks the Signal
strength reading on the Installation Settings menu. When the receiver acquires
the satellite signal, the signal strength will increase. Continue to move the
satellite dish clockwise, and when the signal strength begins to decrease, mark
the location on the mounting pole.

Next, turn the satellite dish counterclockwise in very small, 1 mm (1

32")
