DIRECTV recommends adjusting the azimuth and elevation of the dish while looking at the
101 satellite, adjusting the tilt/skew of the dish while looking at the 119 satellite, and then
performing their fine-tuning/dithering process while looking at the 101 satellite. Please refer to
DIRECTV’s official instructions regarding their dithering/fine-tuning process for more information.
Secure dish and verify adequate signal level and quality:
Check all nuts and bolts and make sure they are tightened to specification. Pay close attention to the
LNB lock down bolts. They must be installed wrench tight to prevent LNB movement.
Check for passing scores (green check marks) on the TV screen that's connected to the powered
DIRECTV receiver for the 99, 101, 103, 110, and 119 satellite transponders. If the satellite receiver
doesn’t pass, then the technician should not leave the site and must improve dish alignment to reach a
passing score.
Checking signal level and quality of SWM channels, if desired:
After aligning the DIRECTV SWM 5-LNB dish (model SL5s), as an optional step, if you want to look at the
signal level and signal quality of all 9 SWM channels, use the following System Setup:

1) After completing the System Setup, press DONE or EXIT to return to the main Run screen.
2) With a coax jumper cable still connected from the ODU / LNB port of your XR-3 meter to the
LNBF output port, press the LNB soft-key to apply power to the LNB.
3) Wait approximately 20 seconds after applying LNB power to SWM LNB before taking
measurements.
4) Use meter’s up/down arrow key buttons to scroll through the 9 SWM channels. You will be able to
see the signal level (left bar graph) and signal quality (right bar graph) and LOCK status of all 9
SWM channels.
