Heading Adjustment
You have mounted the antenna unit facing straight ahead in the direction of the bow.
Therefore, a small but conspicuous target dead ahead visually should appear on the
heading line (zero degrees).
In practice, you will probably observe some small error on the display because of the
difficulty in achieving accurate initial positioning of the antenna unit. The following
adjustment will compensate for this error.
1. Set ship's heading toward a suitable target (for example, ship or buoy) at a range
between 0.125 and 0.25 nautical mile.
2. Transmit the radar at 0.25 nm range and measure the bearing of that target relative to
ship' heading with EBL.
3. Open the Installation menu, and choose Heading Adjust.
4. Press the ENTER key to show the HEADING ADJUST window.
5. Rotate the trackball upward or downward to set the value measured at the step 2 above.
6. Press the ENTER and confirm that the target shows dead ahead on the screen.
