2.11 Measuring the Bearing

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

2.11.1 Measuring 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.

2.11.2 Measuring bearing by EBL

1.Press the EBL/VRM key.

2.Press the A: EBL1 ON (dotted line EBL) or D: 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.

How to measure bearing with the EBL

4. You may hide the EBL/VRM soft keys by pressing the EBL/VRM key.

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.

2.11.3 Various EBL operations

Erasing an EBL, EBL indication: Press appropriate EBL soft key (B or E key), then press the CLEAR key. The EBL is erased and its indication becomes blank.

Erasing, hiding, moving EBL/VRM data boxes: See paragraph 2.10.4.
