To prevent exposure to RF energy, which may be
harmful to people who stand within 36 feet
(11 meters) of the antenna, you can configure up
to two no-transmit zones for areas where crew
and/or passengers frequent (see Figure 39). The
system will disable the transmitter whenever the
antenna is pointing within one of these zones.
Follow these steps to set up a no-transmit zone.
a.
Determine the necessary azimuth range for
the no-transmit zone(s). You will need to
enter, in clockwise order, beginning and
ending azimuths that define the outer
boundaries of the zone(s)
relative to the
antenna’s forward arrow
, which should be
pointing toward the bow (see Figure 40).
b.
Determine the necessary elevation range for
each no-transmit zone(s) (see Figure 41).
NOTE:
Each no-transmit zone must span at least 5°
in both azimuth and elevation.
