Raymarine Combined Pathfinder Radar, RL80CRC PLUS Moving, Reshaping or Deleting a Guard Zone, Off

Chapter 3: Standard Radar Operations 3-21

3.If necessary, use the trackpad to move the corner of the guard zone to the required position. As you move the corner, the width and/or height of the zone changes, but its general sector shape is retained.

Note: To create a 360° guard zone, rather than a sector guard zone, you can either move the corner all the way round to form a circle, or move it back to just the other side of the other outer corner.

4.Press ENTER to drop the corner in its new position and redraw the zone, or CLEAR to abandon the operation and return the corner to its previous posi- tion.

The display shows this zone boundary as a short-dashed line (zone 1) or a long dashed line (zone 2), and the cursor returns to normal control.

5.If required, use the context-sensitive cursor to reposition other corners/ sides of the zone in turn, as described below.

Moving, Reshaping or Deleting a Guard Zone

➤You can move, reshape or delete an existing guard zone using the context- sensitive cursor. To do so:

1. Move the cursor over the guard zone corner or side that you wish to control,

GRD until the letters GRD are displayed.

2.If you wish to delete the whole zone, press CLEAR.

3.Alternatively, if you wish to move the corner or side, press ENTER to take control of it. The zone boundary is displayed as a solid line, and the cursor as a four-headed arrow.

4.Move the corner or side to the new position, as described on the previous page.

Note: To convert a 360° guard zone back to a sector guard zone, take control of any point on the circle, and move it to open up the circle.

5.Press ENTER again to drop the corner or side in its new position, or CLEAR to abandon the operation and return it to its previous position

The radar shows the zone boundary as a short-dashed line

(Zone 1) or a long-dashed line (Zone 2), and the cursor returns to normal control.

6.If required, reposition the cursor and repeat steps 3 to 5 to move the other corners or sides.

➤You can also delete (turn off) a zone by pressing the ALARMS key, and then
