Verify Azimuth alignment

Switch to Sat B (119°) on your on-screen menu, using

Transponders 23, 25, 29 or 31. Verify that signal is also

peaked at 119° by very slightly rotating the antenna around

two Azimuth/Mast clamp bolts.

NOTE: Sat B (119°) signal strength may read different than

Sat A (101°) signal strength, depending on the satellite

fixed. However, because of large Tilt angle to 119° satellite in

Eastern Seaboard states, a small amount of Tilt fine-tuning

adjustment may improve 119° signal strength without

significantly changing 101° signal reading. For these states,

the following Tilt fine-tuning

procedures are recommended:

1. Follow alignment procedures from Step 1 through Step 9;

tighten Elevation and Mast clamp bolts.
