mrtugboat,
Here is the instruction that will get you into the Installation Menu:
• Press the MENU key. The main menu now appears on the screen.
• Press the UP or DOWN Arrow Keys on the cursor pad to select: [Factory]. The factory menu title bar now appears in gray on the right of the screen.
• While you are pressing the CANCEL/HL OFF key, press the MENU key five times to activate the Factory menu.
• On the main menu, press UP or DOWN Arrow Keys to select: [Installation].
• Now select: [Heading Adjustment]
You should 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 (at or near zero degrees). If the target does not appear on the heading line, do the procedure shown below to adjust the heading.
• Set ship heading toward an acceptable target (for an example, a ship at anchor or buoy) with the range between 0.125 and 0.25 nautical mile.
• 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.
• Open the Installation menu and now select: [Heading Adjust].
• Press the ENTER key to display the window for heading adjustments.
• Press UP or DOWN Arrow Keys to set the value measured like the picture below. And then check that the target appears on the heading line.
• Now press the ENTER key to complete the setting.
