What is a radar guard zone?
Use either or both of the two radar guard zones to notify you when a target enters
or exits a specified area around your vessel.
When the radar guard zone is On, the specified area around your vessel that is
defined by the radar guard zone is highlighted on the
Radar
screen.
The radar guard zones are different from the chart guard zone. Use both types of
guard zone to help ensure the safety of your vessel.
See "Set up the radar guard zone" to customize a radar guard zone for your vessel.
