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
context-sensitive cursor.

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

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.
➤ 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.
