Placing a Guard Zone
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.
• Ifyou havealready placeda guard zone,pressing the ALARMS keyallows
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
positionand shape. However,if this position is off-screenat thecurrentrange
setting,or within onequarter of the current rangefrom 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.
The soft keys indicate the current status of the two guard zones.
2. If necessary, press the softkey forthe guard zone yourequire, to toggle the
setting between OFF andON. The soft keys are cleared. If you turned a

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.
