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).
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.
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.
You may also adjust the EBL, in intervals of 90°, by pressing the EBL soft
key.

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 in the RADAR DISPLAY SETUP menu.
Erasing an EBL, EBL indication
Press appropriate EBL soft key, then press the [CLEAR] key. The EBL is erased
and its indication becomes blank.
