6.27.2 How to Manually Acquire a Target
1. On the radar display, use the CursorPad to put the
cursor on a target.
2. Press the right-click button to show the Radar
pop-up menu, shown in the illustration at right.
3. [Acquire Target] is selected. Push the RotoKey to
acquire the target.
After you acquire a target, the radar marks the target
with a broken square and a vector appears within 30 s.
The vector indicates the direction of the target. Within
90 s after you acquire the target, the first tracking step
is finished and the target is tracked continuously. At this
point, the broken square changes to a solid circle.
Note 1: For successful acquisition, the target must be within 0.05 to 16 nm from your
vessel and not hidden in sea or rain clutter.
Note 2: When the capacity for manual acquisition is reached, you cannot acquire
more targets. Cancel tracking of non-threatening targets to acquire additional targets
manually.
