2.17.2 Measuring range & bearing between two targets

The procedure which follows shows how to measure the range and bearing between two targets, using the targets “A” and “B” in the figure below as an example.

1.Operate the Cursor pad to place the cursor on the target “A.”

2.Press the EBL/VRM key to show the EBL/VRM soft keys.

3.Press the EBL1 ON soft key to turn on the EBL1.

4.Press the OFFSET soft key. The origin of EBL1 moves to the cursor position, which is marked with an “X.”

5.Rotate the ENTER knob so the EBL bisects the target “B.”

6.Push the ENTER knob, then press the VRM1 ON soft key.

7.Rotate the ENTER knob to place the VRM1 on the inner edge of the target “B.”

8.Look at the indications for VRM1 and EBL1 to find the range and bearing between the two targets.
