2.17.2Measuring 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.

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.Press the [ENTER] knob.

7Press the VRM1 ON soft key and then rotate the [ENTER] knob to place the VRM1 on the inner edge of the target “B.”

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

9To cancel the offset EBL, press the OFFSET key.
