Finding range and bearing with a floating
VRM/EBL
If you move the centre of a VRM away from

to measure the range and bearing between
two locations on the radar window, such as a
headland and a buoy.
1 From the radar window, press
then
select
VRM/EBL
.
2 Select
VRM/EBL
then 1 (VRM/EBL 1) or 2
(VRM/EBL 1).

5 Select
Set centre
to move the VRM
and EBL centre away from your boat. Use

it is aligned over the first location.
6 Press
to save the new centre
position, then press
and reselect the
VRM/EBL.
7 Select
Adjust
to adjust the VRM and the
EBL so that you can align them with the
second location. Use:
•
and to decrease and increase the
radius of the VRM until it touches the
second location to measure the range.
•
and to move the EBL until it
touches the second location to
measure the bearing.
8 The range and bearing of the target is
shown at the bottom of the screen.
9 If you want to hide (or change the settings

heading line, press
then select Radar.
10 To clear the VRM/EBL display, press
and repeat steps 1 and 2. Then set Enable
to .
If you want to find the range and bearing
between two other locations, repeat the
sequence using the other VRM/EBL. This
is shown in a different pattern in the radar
window.
