Testing the System
If necessary, adjust the Elevation
If you still haven’t picked up the satellite signal, you may need to
adjust the elevation.
1. Return the LNB support arm to the original compass
direction.
2. Tighten one of the three nuts on the support sleeve so the
dish will not rotate left and right.
3. Loosen the elevation nut on the LNB support arm so the dish
can move up and down.
4. Adjust the dish upward slightly to increase the elevation one
tick mark. Pause to listen for five seconds.
5. If you still don’t hear the continuous signal tone, move the
dish back to its original elevation, then move the dish down
one tick. Pause to listen for five seconds.
6. Continue rotating the dish further up and down one tick
mark at a time. (For example, you’ve tested the system two
tick marks to the right, then you move two tick marks left to
the original position, then two more tick marks left, etc.)
Make sure to pause for five seconds before changing the dish
position.
Did you hear one continuous tone?
NO Go to the next step, Troubleshooting the System Test,
page 41.
YES Your system is working and you have located the precise
direction to point the dish. You may want to pick out a landmark
to help you remember the direction. Skip to Disconnecting Test
