Figure 3-12: Placing a VRM
2. If required, use the trackpad controls to change the radius (range) of the
VRM circle and the angle of the EBL until they cross the required target.
The range and bearing information in the VRM/EBL data box is updated
as you move the cursor.
3. Press
ENTER
to drop the VRM/EBL. The radar shows this
VRM/EBL as a short-dashed line, and the cursor returns to normal control.
4. Read the range and bearing to the target or point, which is shown in the
VRM/EBL data box.
5. If required, you can move or delete the VRM/EBL data box using the con-
text-sensitive cursor.
➤
To place a VRM/EBL when one is already displayed:
1. Press VRM/EBL to display the VRM/EBL soft keys.
The labels for the two left-hand soft keys indicate the current status of the
two VRM/EBLs.
2. Press the soft key for the VRM/EBL you require, to toggle the setting from
OFF
to
ON
.
The soft key labels are cleared, and the radar picture shows the VRM/EBL
and its associated data box.
3. Position the EBL/VRM using the trackpad, and press
ENTER
to drop it.
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.
Moving an Existing VRM/EBL
You can move an existing VRM/EBL using the context-sensitive cursor. You
can control the VRM and EBL separately or both together.
