MARPA status
The MARPA status can identify if a heading sensor is on the network
and that the radar is receiving heading information essential for
MARPA calculations.
Reset device ID
Should a radar be connected to the network that has been
connected to a dual radar network in the past, it might not be
detected by the system because it might have an invalid Device ID.
With the radar connected and powered up, select the Reset Device
ID button to resolve this problem.
Ú
Note: This procedure must be performed with only one radar
on the network, and only applies where a network combines an
older NSS with other MFDs.
Adjust antenna height
Set the radar scanner height relative to the water surface. The Radar
uses this value to calculate the correct STC settings.
Adjust range offset
(Pulse Radar only)
The radar sweep should commence at your vessel (a radar range of
zero). You may need to adjust the radar range offset to achieve this.
If this is set incorrectly, a large dark circle in the center of the sweep
might occur. You might notice straight objects such as straight sea
walls or piers having curves or an indentation. Objects close to your
vessel may appear “pulled in” or “pushed out".
Adjust the range offset as below when the vessel is about 45 to 90
m (50 to 100 yards) from a straight-walled jetty or similar feature
that produces a straight line echo on the display.
• Point the boat towards the jetty
• Adjust the gain setting until a reasonably good image of the jetty
echo is displayed
