NorthStar Navigation 8000I Target presentation, Make small targets more easy to see

25 Target presentation

This section explains how to:

•make small targets more easy to see

•turn off or customize target trails

•remove target trails from the radar screen

25.1Make small targets more easy to see

You can turn the Expand Target feature On or Off. When it's On, all the targets on all the Radar screens appear larger. This is particularly useful if you have several small targets in view and want to make them easier to see by extending them outwards along a radial line.

The default setting is Off.

The resolution decreases as the size increases, so use this feature only when target

detection and visibility is more important that the quality of the display.

To make all the targets appear larger:

1.Display the Radar screen and the control panel. If you can't see the

Presentation button, select Return.

2.Select Presentation.

3.The Expand Target button shows the current setting. Select the button if you want to toggle to the other setting.

4.The new setting is applied immediately to all the Radar screens and stays until you change it again.

5.When you are finished, select Return.

25.2Turn off or customize target trails

You can set the trail that each target leaves on your Radar screen to last for 15 seconds, 30 seconds, 1 minute, 3 minutes, or indefinitely. You can also turn Off target trails completely. Off is the default.

If you're using true motion, stationary targets will leave a trail. If you're using relative motion, any target that is moving relative to your vessel will leave a trail.

To turn off or set the length of target trails:

1.Display the Radar screen and the control panel. If you can't see the

Presentation button, select Return.

2.Select Presentation.

3.Select Target Trails and a drop down list of choices appears.
