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 Trackball to place the cursor on the target “A.”

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