Change the rain setting | NorthStar Navigation 8000I guide

22.7Change the rain setting

The rain setting is a combination of the FTC (Fast Time Constant) that defines the leading edge of a rain shower but suppresses echoes from the following body of rain, so that any targets in the rain shower area are shown more clearly; and the STC (Sensitivity Time Control) that helps to suppress echoes from any rain around the radar itself.

If the rain setting is too low, there'll be excessive rain clutter displayed whenever it's raining. If the rain setting is too high, very large targets such as the coastline will appear to be hollow.

The rain setting is shown as a percentage. 0% is the default.

NOTE: The Rain setting is returned to the default value of 0% every time that the radar is restarted.

To change the rain setting:

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

Adjust Radar button, select Return.

2.Select Adjust Radar.

3.Select Rain and a slider box appears. The current setting is shown as a line within a solid bar of color and as a percentage.

4.Drag the line, or use the rotary knob, to change the rain setting.

5.Select OK to confirm the new setting. The new setting is applied immediately to all the Radar screens and stays until you restart the radar.

6.When you are finished, select Return.

22.8Reduce interference from other radars

Another vessel's radar operating at the same frequency as your radar can cause interference patterns on your Radar screen.

Interference patterns always appear in a different place with each sweep. They can be randomly scattered bright dots or dotted lines that extend from the centre to the edge of your Radar screen, often producing a spiral pattern. Generally, the stronger the interference, the wider the interference lines.

You can use the interference rejection feature to reduce both the interference patterns, and the width of the interference lines.

To reduce interference:

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

Presentation button, select Return.

2.Select Presentation.

3.Select Interference Rejection and a drop down list appears. There are four choices:

Off. Turn interference rejection Off.
