Antenna Pointing - Transmitter, The manual cross-polarization function can be used to adjust the Manual antenna and peak the antenna’s transmit polarization for

maximum isolation. You can also use manual pointing to adjust polarization after failing the automatic cross-polarization test.

1.Enter C at the Installation Menu prompt. The Antenna Pointing - Transmitter, Manual screen appears.

Otherwise, the screen shows the current queue position until the test can be run. When the Test Status field shows Active the test can be run. The result of the test is shown in the Result: field, where a transmitter isolation value is reported.

2.Make small, one-degree or less changes in polarization while observing the transmitter isolation. Peak the transmitter to the highest possible transmitter isolation value.

3.Press Enter to return to the Installation Menu.

Antenna Pointing - Transmitter, Automatic cross-polarization (ACP) is used for a rapid Pass/Fail Automatic test of the antenna’s transmit polarization adjustment. If you pass

ACP the unit is enabled and no further antenna pointing is needed.

1.Enter B at the Installation Menu prompt. The Antenna Pointing - Transmitter, Automatic screen appears.

Otherwise, the screen shows your current queue position until the test can be run. (Sometimes a number of installers will be pointing their antennas at the same time. You may have to wait for the test to be run, and are placed in a queue until it can be run.)

The result of the test is shown in the Result: field. PASS means the transmit modem will be enabled and the system should be operational. FAIL means the transmit modem will be disabled and the dish pointing needs to be checked.

2.Whether you pass or fail, press Enter to return to the

Installation Menu.

3.Enter z to return to the Main Menu.

4.At the Main Menu enter c. The Satellite Interface Statistics Menu appears (see Figure 83).

5.Enter a. The Display Main Statistics screen appears. Confirm the SQF is greater than 31 and that the transmitter is available.

6.Enter z to return to the Main Menu.
