5.2.3.9. POL TRIM

Individual

Polarization Trim

offset adjustment to optimize the Auto-Polarization on this satellite.

Some satellite beams aimed at certain geographic areas are purposely skewed in polarization.
During initial setup of this satellite selection, you will have to trim/offset auto-polarization by the
amount of skew of the satellite beam. Once this adjustment has been set, and saved, auto-
polarization will keep the polarization optimized during ship motion and geographic travel. Range
of acceptable input is +/- 40 degrees.

If you do

NOT

know what amount of offset is required for this satellite refer to the procedure in

paragraph 5.3.

If you know what amount of +/- polarization offset is needed for this SAT, continue with the steps
below:

Press the NEXT key to SELECT this sub-menu parameter for adjustment.

A cursor will appear under the rightmost digit. Press

▲

arrow key to increment the Pol Trim

plus one degree. Press

▼

arrow key to decrement the Pol Trim minus one degree.

Press the SAVE key to save the POL TRIM parameter for this SAT.

If you want to edit any of the other

default

values that are loaded with preset, press the

▼

arrow key to go to the next sub-menu parameter.

If you do not want to edit any other sub-menu parameters, press SAVE again to exit the sub-
menu and return to the SAT main menu display. From there you can press the

▼

arrow key

to go to next SAT numeric menu choice or to the Factory Settings menu choice.

5.2.4. SAT2 - Second Satellite Parameters

Access all of the SAT2 individual parameters via a sub menu. If a second SAVED satellite if not needed,
preset SAT2 to empty/blank so NEXT will skip over this selection when you are switching satellites.

All of the SAT2 parameters are set exactly the same way that the SAT1 parameters were set, but would
be set to different choices. Refer to the parameter setting information in the SAT1 – First Satellite
Parameters paragraphs to set PRESET, NAME, LON, FREQ, ALT FREQ, BAUD, FEC, NID and POL
TRIM for a second satellite you wish to use periodically.

5.2.5. SAT3 - Third Satellite Parameters

Access all of the SAT3 individual parameters via a sub menu. If a second SAVED satellite if not needed,
preset SAT3 to empty/blank so NEXT will skip over this selection when you are switching satellites.

All of the SAT3 parameters are set exactly the same way that the SAT1 parameters were set, but would
be set to different choices. Refer to the parameter setting information in the SAT1 – First Satellite
Parameters paragraphs to set PRESET, NAME, LON, FREQ, ALT FREQ, BAUD, FEC, NID and POL
TRIM for a third satellite you wish to use periodically.

5.2.6. SAT4 - Fourth Satellite Parameters

Access all of the SAT4 individual parameters via a sub menu. If a second SAVED satellite if not needed,
preset SAT4 to empty/blank so NEXT will skip over this selection when you are switching satellites.

All of the SAT4 parameters are set exactly the same way that the SAT1 parameters were set, but would
be set to different choices. Refer to the parameter setting information in the SAT1 – First Satellite
Parameters paragraphs to set PRESET, NAME, LON, FREQ, ALT FREQ, BAUD, FEC, NID and POL
TRIM for a fourth satellite you wish to use periodically.
