Setting the Heading Calibration
The heading calibration rotates the radar image on the screen to line it up with the displayed chart
and the compass. Accurate heading calibration is especially important when overlaying the radar
image onto the chart.
1. Make sure the heading sensor is calibrated according to the
manufacturer's instructions.
When sea trialing the vessel, set a straight course for a solid object such as
a lighthouse, jetty, or radar nav marker that is at least 1 nm away as
referenced on the chart.
2. Turn on the radar overlay feature: Press CHART to display the chart and press Overlay to
display radar echoes overlaid on the chart.
3. Set the chart rotation to North-up by pressing Rotate several times until North up is
displayed.
4. Find a target that appears on both the radar image and the chart. An appropriate choice
would be a land pattern or solid object about a mile or more from the vessel, with a fixed
point, such as a jetty, lighthouse, or pier. (Avoid beaches and buoys as these may have radar
images that don't align with the chart.) Zoom in as necessary to place identifiable objects
near the outer edge of the screen.
5. Press the Control key so that it displays Radar .
6. Press Page 2 , Page 3 , Page 4 , and Install... .
7. Press Heading Calibrate and press the Cursor Pad left and right to rotate the radar image so
that the radar target matches its compass heading on the chart and lines up on top of the
position shown on the chart.
