Measuring Range and
Bearing Between
Targets (FLOAT)
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.
3. Alternatively, if you wish to move the floating VRM/EBL, press
ENTER to
take control of it and move it using the trackpad.
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 posi-
tion.
➤ To unfloat a floating VRM/EBL using the keys:
1. Press
VRM/EBL to display the VRM/EBL soft keys.
2. Press the
FLOAT soft key.
3. Press the
UNF LOAT 1 soft key to unfloat VRM/EBL1, or the UNFLOAT 2 soft
key to unfloat VRM/EBL2.
The soft keys are cleared, and the VRM/EBL is repositioned with its ori-
gin at your vessel’s position.
