To move the VRM and/or EBL:
1. Move the cursor over the VRM or EBL you wish to change. If you wish to
change the VRM and EBL together, move the cursor over the intersection
of VRM/EBL. The cursor text indicates the current object as VRM, EBL,
or VRM/EBL.
2. Press
ENTER
to take control of the object. The object(s) under control is
displayed as a solid line, and the cursor as a four-headed arrow.
3. Move the EBL to the new angle and/or change the VRM radius (range)
using the trackpad controls.
4. Press
ENTER
again to drop the VRM/EBL in its new position, or
CLEAR
to
abandon the operation and return the VRM/EBL to its previous position.
The radar shows the VRM/EBL as a short-dashed line (VRM/EBL1) or a
long-dashed line (VRM/EBL2), and the cursor returns to normal control.
Deleting an Existing VRM/EBL
➤
You can delete a VRM/EBL by using the
VRM/EBL
key to display the soft
keys, and pressing the required
VRM /EBL
soft key to toggle the setting from
ON
to
OFF
.
➤
Alternatively, you can delete an existing VRM/EBL using the context-
sensitive cursor. To do so:
1. Move the cursor over the VRM/EBL you wish to control, until the letters
VRM, EBL,
or
VRM/EBL
are displayed.
2. Press
CLEAR
.
This has the same effect as turning the VRM/EBL off using the
VRM/EBL soft keys. It turns off the VRM/EBL pair, irrespective of the
cursor text: you cannot turn off VRMs and EBLs independently.
Measuring Range and Bearing Between Targets (FLOAT)
You can measure the range and bearing between any two points on the radar,
such as two targets, using the Pathfinder Plus Radar’s Float function. This
allows you to move the origin of a VRM/EBL away from your vessel’s
position and onto a target. You can then change the angle of the EBL, relative
to its new origin, to obtain the bearing between two points. The radius of the
VRM can also be adjusted to determine the distance between two points.
Floating a VRM/EBL
Note: You can float a VRM/EBL pair using either the soft keys or the context-
sensitive cursor. The procedure for using the cursor is the same as for moving
