The screen will display a green ring with black center (assuming you are using the standard green
screen colors).
If this gain setting does not display the green ring on the screen, try other gain settings until the
green ring is displayed clearly. Using too high a gain setting may saturate the image.
10. Press Page 3 , Page 4 , and Install... .
11. Press Trigger Delay . Set the trigger delay to zero by pressing " 000 " on the keypad.
12. Increase the trigger delay by pressing the Cursor Pad to the right (or enter a larger number
on the keypad). The black circle will shrink as you increase the trigger delay. Set the trigger
delay so that the black center just disappears, with a one or two dots remaining in the very
center of the screen.
Method 2:
The vessel should be located 50 to 100 yards from a straight jetty or other landmark that should
produce a straight-line echo on the screen.
1. Adjust the gain to obtain a reasonably good image of the jetty echo.
2. Adjust the Trigger Delay to make the jetty echo appear as a straight line on the screen as
shown in Figure 17.

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 as follows:
• on the 6000i, press CHART to display the chart and press Overlay to display radar echoes
overlaid on the chart.
