24.3 Find range and bearing with fixed VRM/EBL
Use one, or both, of the VRM/EBL (Variable Range Markers/Electronic Bearing
Lines) to show the precise range and bearing of a target from your vessel. This is a
fixed VRM/EBL.
You can also use the cursor (See "Find range and bearing with the cursor").
To find the range and bearing of target with a fixed VRM/EBL:
1. Display the Radar screen and control panel. If you can't see the
Range and Bearing button, select Return.
2. Select
Range and Bearing.
3. The
EBL Reference button shows the current setting. Select:
ƒ North if you want the EBL bearing to be referenced to North
ƒ Relative if you want the EBL bearing to be relative to your vessel's
position
4. Select
VRM/EBL 1 to show the control panel for VRM1 and EBL1. If
Show VRM/EBL 1 is toggled Off, select it to toggle it On. Note
that if the VRM/EBL 1 position is not shown initially when you
toggle it On, because it's outside the current radar range, it'll be
adjusted to appear at one third of the current range.
5. The Radar screen shows:
ƒ VRM 1. A thin, circular, dotted line centered around your vessel. The
radius is set at the most recent position.
ƒ EBL 1. A thin dotted line extending from your vessel to the edge of
your Radar screen. The bearing is relative to your vessel. The
default angle is 045° Relative.
ƒ A message box showing the range and bearing of the VRM/EBL. If
you can't see this, check the box next to VRM/EBL 1 Data to

6. To show the range readout, you can either:
ƒ drag VRM 1 across the PPI until it touches the target, or
ƒ select Adjust VRM 1 then use Up or Down or the rotary knob
to increase or decrease the radius of VRM1 until it touches the
target.
7. The 8000i updates the range readout with each change in radius.
Select OK when you are at the target.
8. To show the bearing readout, you can either:
ƒ drag EBL 1 across the PPI until it touches the target, or
ƒ select Adjust EBL 1 then use Up or Down or the rotary knob
