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")
