RT installation
Following the RT antenna installation instructions in chapter 6,
you pointed the antenna approximately toward the HT, using the
boresight. This section explains how you more accurately point

To point the antenna, follow steps 1 through 13 below.
Before you can point the antenna using the voltmeter, you must
first put the IDU into Install mode and select the (RT) ODU
frequency, as follows:
1. From the IDU (CCM) LCD main menu, select Install mode,
and press the Enter button.
