How to manually acquire a target

Acquire a target from the Control Unit
Use the trackball to put the cursor on the target you want to acquire. Push the ACQ/
ACT key.
Acquire a target by the trackball module
1. Put the cursor on the target to acquire.
2. Push the right button to show the context-sensitive menu then select [Target Data/
ACQ/ACT] to acquire the target.
The plotting symbol is drawn by a dashed circle during the initial acquisition stage. A
vector appears approximately one minute after acquisition. The vector indicates the
motion trend of the target. If the target is consistently detected for three minutes, the
plotting symbol changes to a solid circle. If acquisition fails, the target symbol blinks.
Note 1: For successful acquisition, the target should be within 0.2 to 24 nm (or 32 nm,
depending on initial setting) from own ship and not obscured by sea or rain clutter.
Note 2: You are alerted when the capacity of manual acquisition is 95% and 100%.
These alerts are Alert 524 "TT MAN ACQ 95%" and Alert 525 "TT MAN ACQ 100%".
If the capacity is 100% you cannot acquire more targets. Cancel tracking of non-
threatening targets if you wish to acquire additional targets manually.
Note 3: When a target being tracked nears another target being tracked, the targets
may be "swapped". When two targets acquired either automatically or manually come
close to each other, one of the two may become a lost target. If this occurs, manual
re-acquisition of the lost target may be necessary after the two have separated.
Note 4: You can reuse a target number. This is useful when you acquire the "wrong"
target. Drag and drop the symbol onto the correct target.
