g. When the pair of elevation readings matches, check the
azimuth readings again to ensure that they were not altered
during elevation adjustment. Make any adjustments as
necessary.
h. Lock down the azimuth using a socket wrench with an
extension.
i. Measure the top and bottom elevation readings again to
ensure that they have not been altered during azimuth
lockdown.
j. Lock down the elevation. After lockdown, the two azimuth
readings and the two elevation readings should be within
15 points of each other.
k. When finished, press Advance . The DAPT display should
read:
When the
FindSys done
message appears, proceed to
step 2 on page 23.
The following message may also appear:
This message indicates that an error has occurred. If this message
appears, you must resubmit the installation parameters at the IDU
and restart the pointing process, beginning with coarse pointing.
Note: Because slight movement of the antenna occurs
during lockdown, always measure the elevation readings
again after locking down the azimuth. When this second
pair of elevation readings matches, you can lock down the
elevation.
Note: It could take anywhere from 2 to 10 minutes before
this message appears.
