In setting a guard zone, it is necessary to adjust radar tuning,
gain, sea clutter suppression and rain/snow clutter suppression
to ensure that target echoes are displayed in the optimum
conditions. The guard zone alarm is not generated for the
targets that are not detected by radar.
The guard zone function is used to set a zone at an arbitrary range and to sound an alarm if
a target intrudes into this zone.
Refer to section 3.4 "Set Guard Zones" on how to set guard zones.
