26 Use the radar guard zones
This section explains what the radar guard zones are, and how to:
•
turn a radar guard zone on or off
•
set the sensitivity of the radar guard zone alarm
•
customize a radar guard zone
Any changes are global, meaning that they'll apply to all the Radar screens.
26.1 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.
26.2 Turn a radar guard zone on or off
Two radar guard zones are available, Guard Zone 1 and Guard Zone 2. You can
turn either or both of the radar guard zones On or Off.
If you turn a radar guard zone Off, it's immediately removed from all the Radar
screens and any targets within that radar guard zone are no longer monitored.
