You must allow the IDU enough time to track and register the
signal strength.
6. After acquiring a signal, adjust the azimuth to obtain the
highest signal quality.
7. Go to Peaking the azimuth signal on page 72 and follow the
instructions there.
If you cannot detect a signal
If, after following the instructions in Setting the azimuth, you do
not detect a signal, perform the following instructions:
1. Repeat steps 3 through 5 in Setting the azimuth on page 70.
(Adjust the reflector to about 1
/
8
inch to the right of the
approximate azimuth.)
2. Keep moving the antenna reflector to the right a little at a
time until you detect a signal.
3. If there is no signal, sweep back
1
/
8
inch at a time to the left
until you detect a signal.
If you still cannot detect a signal, there may be an error. If there is
no signal, perform the following quick checks.
1. Check the coaxial cable connections at the LNB, IDU, and all
the connections in between.
2. Make sure there are no obstructions such as trees blocking
the signal.
3. Make sure you recorded and properly set the azimuth,
elevation, and polarization values.
4. Verify the azimuth setting by moving 15 ft in front of or
behind the antenna and taking another compass reading.
Metal near the compass, such as a car or even a belt buckle,
can give a false reading.
5. Point the front of the antenna reflector to the left of the
estimated bearing.
6. Go back to step 3 in Setting the azimuth on page 70 and try
again.
When you have acquired a signal and adjusted azimuth to obtain
the highest signal quality, go to Peaking the azimuth signal on
page 72 and follow the instructions there.
Note: Make small adjustments (not more than
1
/
8
inch of
azimuth as measured at the mast). Wait 5 sec between
adjustments to give the IDU enough time to lock onto the
satellite signal.
