How to Acquire and Track Targets

Place the cursor on the TT acquisition mode indicator, then press the left button. The
indication changes, depending on the TT mode selected (See section 3.4). The table
below shows the indication changes based on mode selection.
TT mode selected
[Manual 50]
[MANUAL 25•AUTO 25]
[AUTO 50]
The plotting symbol is drawn by broken lines during the initial acquisition stage. A vec-
tor appears in about one minute after acquisition indicating the target's motion trend.
If the target is consistently detected for three minutes, the plotting symbol changes to
a solid circle. If acquisition fails, the target plotting symbol blinks and disappears short-
ly.

How to manually acquire targets

You can acquire targets manually using one of the following two methods:
Using the control unit (RCU-028)
1. Place the cursor on the target to acquire.
2. Press the TGT ACQ key.
Using the menu
1. Select the operational display area, then press the right button. The [CURSOR]
menu is displayed.
2. Select [TARGET DATA/ACQ], then push the ADJUST knob.
3. Place the cursor on the target to acquire, then push the ADJUST knob.
Note 1: For successful acquisition, the target to be acquired should be within 0.1 to
24 nm (or 32 nm, depending on initial setting) from own ship and not obscured by sea
or rain clutter.
Note 2: When the capacity for manual acquisition is reached, the message "TT TAR-
GET FULL(MAN)" appears at the screen bottom. 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. Should this happen,
manual re-acquisition of the Lost Target may be required after the two have separat-
ed.

How to automatically acquire targets

Targets are automatically acquired when the TT mode is set to either [MANUAL
25•AUTO 25] or [AUTO 50] and a target enters the acquisition zone (see
section 3.15). The maximum tracking distance (24 NM or 32 NM) is set at installation.
