Bearing - Furuno 1751 Operator's Manual

Measuring Range and Bearing
2. OPERATIONAL OVERVIEW
Note that the range to the cursor always varies with trackball operation. The VRM and its
indication, however, are automatically fixed when the
VRM
touchpad is pressed, or 10
seconds elapses without trackball operation.
Unit of range measurement
You can display the range readouts of the VRM and the cursor in nautical miles or
kilometers. This selection is done at installation. Refer to page 6-19.
Bearing
There are two ways to measure the bearing of a target: by the cursor or by the Electronic
Bearing Line (EBL).
Cursor
For an estimate of the bearing to a target, operate the trackball to place the cursor intersec-
tion on the center of the target. The bearing to the target appears at the bottom of the screen.
EBL
Press the
EBL
touchpad to display an EBL. (The EBL is the dotted line.) Position the EBL
so it bisects the target by operating the trackball, and press the
EBL
touchpad again to fix the
EBL to the position. Check the bearing readout to find the bearing of the target.
To erase the EBL, press and hold down the
EBL
touchpad for about three seconds.
