6.  Radar

The purpose of the guard alarm is to provide audio and visual warnings against targets 
(vessels, islands, landmasses, etc.) when a radar target enters the area you select.

You can set a guard zone by two methods. Use the Radar pop-up menu or the soft 
controls ([Guard Zone]

→[Zone] 1(2)). The procedure shown below shows how to set 

a zone with the pop-up menu.

1.

Push the right-click button to show the Radar pop-up menu.

2.

Use the RotoKey to select [Set Guard 1] or [Set Guard 2].

3.

Use the CursorPad to put the cursor at point A for the guard zone then push the 
left-click button.

4.

Use the CursorPad to move the cursor to point B for the guard zone then push the 
left-click button. 

Note 1: To set a 360-degree guard zone, set the same bearing for both the posi-
tion A and position B.

Note 2: The location of points A and B control the shape of the guard zone. Below 
are three examples.
