or unfloating a VRM/EBL pair, as described below; however, as it is more dif-
ficult to locate the VRM/EBL origin when it is over the centre, you will proba-
bly find it easier to use the keys in this case.
➤
To float a VRM/EBL pair using the keys:
1. If one is not already present, place a VRM/EBL pair as described in the pre-
vious section.
2. Press
VRM/EBL
to display the
VRM/EBL
soft keys.
3. Press the
FLOAT
soft key. The soft keys are updated, with the relevant
options displayed.
4. Press the
FLOAT 1
soft key to float VRM/EBL1, or the
FLOAT 2
soft key to
float VRM/EBL2.
The soft keys are cleared. The cursor is positioned over the origin of the
VRM/EBL, over your vessel. The cursor has control of the VRM/EBL, as
indicated by the four-headed arrow, the text
FLT in inverse video, and the
solid VRM/EBL line.
5. Use the trackpad to move the origin of the VRM/EBL to the required posi-
tion (over the first target).
6. Press
ENTER
to drop the VRM/EBL in its new position, or
CLEAR
to aban-
don 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.
7. Use the context-sensitive cursor to take control of the VRM and/or EBL, to
obtain the range and/or bearing to a second target, as previously described.
8. Read the range and bearing information from the VRM/EBL data box.
Moving and Unfloating a Floating EBL
You can move or unfloat a VRM/EBL that has been floated. You can unfloat a
VRM/EBL either by using the context-sensitive cursor or by using the
FLOAT
soft key options.
➤
To move or unfloat a floating VRM/EBL using the cursor:
1. Move the cursor over the origin of the VRM/EBL you wish to control, until
the letters
FLT
are displayed.
2. If you wish to unfloat the VRM/EBL, press CLEAR . The origin of the
VRM/EBL is reset to your vessel’s position.
