Heading Adjustment
You have installed the antenna unit so that the unit faces toward the bow. A target at the front of
the boat and aligned with the bow must appear on the heading line (zero degrees). If the target
does not appear on the heading line, do the procedure shown below to adjust the heading.
1. Set ship heading toward an acceptable target (for example, ship at anchor or buoy) at a range
between 0.125 and 0.25 nautical mile.
2. Transmit the radar at the range of 0.25 nautical mile and measure the bearing of that target
relative to ship heading with an EBL.
3. Open the Installation menu and select [Heading Adjust].
4. Press the ENTER key to show the window for heading adjust.
5. Press or to set the value measured at the above step 2. Check that the target appears
on the heading line.
6. Press the ENTER key to complete the setting.
