Verify Azimuth alignment -
Switch to Sat B (119°) on your on-screen menu, using J
Transponders 23, 25, 29 or 31. Verify that signal is also
peaked at 119° by very slightly rotating the antenna around
\ ~:~/ the penciled marking on the mast. Once satisfied, tighten the
two Azimuth/Mast clamp bolts.
[ ~EI NOTE: Sat B (119°) signal strength may read different than
Sat A (101°) signal strength, depending on the satellite
.0 transmission patterns in the area. You only need to see
Verify Azimuth whether Sat B (119°) is peaked and not try to compare
Alignment signal strength numbers. It's OK to be close but not at the
peaks for both locations simultaneously.
Fine-tune the Elevation
Use Sat B (119°) or Sat A (101°) on-screen signal meter. While
holding the LNB Arm, slightly loosen the two Elevation nuts.
~ I 0 ,. ...;, I ~ Move it up/down slightly and observe the signal strength on the

~.6 Verify satellite signals
~~: Confirm the final signal-peak readings at all three satellite
..locations. Sat C (110°, Transponders 8,10 and 12.) should
be aligned automatically.
NOTE 1: Occasionally, you may see a transponder at Sat A
(101°), Sat B (119°) or Sat C (110°) not active, it is
/ --~\ possible that this transponder is reserved for upcoming
programming expansion. Switch to other transpo~ders at the
same satellite location to verify that you have good readings
and that your antenna alignment is satisfactory.
Fine-tune the NOTE 2: In most of the U.S., the Tilt Adjustment should be
Elevation 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.
2. Fine-tune Tilt Adjustment first by +3 degrees and then
-3 degrees. Tilt is optimized when you see the 1010
--signal reading essentially unchanged and 119° signal
