Placing and positioning guard zones on the Pathfinder Plus Radar display is 
quick and easy.

•

If a guard zone is not already displayed, you can place one using the 
ALARMS key.

•

If you have already placed a guard zone, pressing the ALARMS key allows 
you to toggle either guard zone on or off.

Note: When you turn on a guard zone, it is normally displayed in its last-used 
position and shape. However, if this position is off-screen at the current range 
setting, or within one quarter of the current range from your vessel, the guard 
zone is placed at its default position and shape instead. This is at one third 
(Zone 1) or two thirds (Zone 2) of the current range, as a sector zone occupy-
ing 30° either side of the ship’s heading marker.

➤ To place a guard zone:

1. Press ALARMS. The soft keys are displayed.

            u

The soft keys indicate the current status of the two guard zones.

2. If necessary, press the soft key for the guard zone you require, to toggle the 

setting between OFF and ON. The soft keys are cleared. If you turned a 
guard zone on, it is displayed in its last-used position with one corner under 
cursor control.

The radar picture shows the guard zone as a four-sided shape bounded by 
a solid line (or a circle if previously set as one).

The cursor is positioned over an outer corner of the zone as shown in 
Figure 3-14. The cursor has control of this corner, as shown by the text 
GRD in inverse video, the four-headed arrow, and the solid guard zone 
boundary.
