2.11Measuring the Bearing

There are two ways to measure the bearing to a target: by the cursor, and by the EBL (Electronic bearing Line).

2.11.1Measuring bearing by cursor

Use the trackball to place the cursor at the center of the target. The bearing to the target appears in the range and bearing box at the bottom right-hand corner on the screen.

2.11.2Measuring bearing by EBL

1.Press the [EBL/VRM] key.

2.Press the EBL1 ON (dotted line EBL) or EBL2 ON (dashed line EBL) soft key to select the desired EBL. The selected EBL’s indication, at the bottom of the screen, is highlighted.

3.Rotate the [ENTER] knob to bisect the radar target with the EBL. Read the EBL indication to find the bearing to the target.

4.You may erase the EBL/VRM soft keys by pressing the [EBL/VRM] key.

How to measure bearing with the EBL

Note: The bearing to a target may be shown relative to own ship’s heading (Relative) or True bearing (requires heading data). This may be done with “EBL REFERENCE,” which is in the RADAR DISPLAY SETUP menu.
