12. Do the same procedure for [EBL2] and [VRM2] to measure the range and bearing
between two other targets (target C and D), use EBL2 and VRM2 similarly.

Collision assessment by offset EBL
The origin of the EBL can be moved to enable measurement of range and bearing be-
tween any targets. This function is also useful for assessment of the potential risk of
collision.
1. Move the EBL origin on the target A,
following "How to offset an
EBL" on page 1-24.
2. Right-click to quit the offset EBL.
3. After waiting for a few minutes, click the appropriate EBL icon to operate the EBL.
The icon turns yellow.
