Figure 2-8: Radar Display with an Offset Center
➤
To return the center of the radar picture to the center of the screen, repeat step 1
and then press the
CLEAR
key. The center is always reset to the center of the
display when you turn on the Radar display.
Note: When the center is offset, additional range rings are displayed to the
edge of the radar picture, at the standard ring interval for the current range. If
you have selected the longest range scale, you cannot offset the center.
Hiding the Ship’s Heading Marker (SHM)
The radar picture includes the ship’s heading marker, which is a line from your
vessel’s position to the edge of the picture at the vessel’s current heading. In
the standard Head Up mode, the heading marker is always a vertical line.
If you wish to check for small targets that may be hidden under the heading
marker, you can hide it momentarily using the context-sensitive cursor.
➤
To hide the heading marker:
1. Position the cursor over the heading marker, so that the text
SHM
is dis-
played.
2. Press and hold
CLEAR
. The heading marker is hidden until you release the
CLEAR key.
