Bearing and distance measurement

This radar has two sets of Electronic Bearing Lines (EBL) and Variable Range Markers (VRM) to indicate the
target direction from your vessel to a target.
D Using the EBL and VRM
1. Move the cursor onto a target.
2. Push [EBL 1 (VRM 1)]/[
the EBL 1 and VRM 1 markers.
3. Push [◄] or [►] to rotate the Electronic Bearing
Line (EBL), and push [▲] or [▼] to increase or
decrease the Variable Range Marker's (VRM) ring
size.
• The EBL/VRM 1 readout in the lower left corner of
the screen indicates the target bearing and distance
in orange.
4. Push [ENTER]/[
VRM 1.
• The EBL 1/VRM 1 readout changes to black.
5. Move the cursor onto another target.
6. Hold down [EBL 1 (VRM 1)]/[
1 second to move the EBL 1 and VRM 1 to the
cursor.
L Hold down [EBL 1 (VRM 1)]/[
second again to move the EBL 1 and VRM 1 to the
original place.
7. Push [EBL 1 (VRM 1)]/[
EBL 1 and VRM 1.
TIP: The indication may differ, depending on the
"Bearing Mode" and "Bearing Reference" setting.
