DISTaNCE aND DIRECTION MEaSuREMENTS
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)]/[
] to display
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]/[
] to apply the EBL 1 and
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)]/[
] for
1 second to move the EBL 1 and VRM 1 to the
cursor.
L
Hold down [EBL 1 (VRM 1)]/[
] for 1
second again to move the EBL 1 and VRM 1 to the
original place.
7.
Push [EBL 1 (VRM 1)]/[
] to clear the
EBL 1 and VRM 1.
TIP:
The indication may differ, depending on the
“Bearing Mode” and “Bearing Reference” setting.

Bearing Reference
• 0 to 359.9°R: Relative direction, clockwise from
the vessel’s bow. (when “360°R”
is selected)
•
P/S 0 to 180°R: Relative direction, left or right
from the vessel’s bow.(When
“PT/SB” is selected)
• 0 to 359.9°T:
True bearing. (When “True” is
selected in both Bearing Mode
and Bearing Reference.)
L
Bearing data is required.
• 0 to 359.9°M: Magnetic bearing. (When
“Magnetic” is selected in Bearing
Mode and “True” is selected in
“Bearing Reference.”)
