Acquisition Zone

The acquisition zone functions both to alert you targets in a specific area and acts as
an automatic acquisition area when automatic target acquisition is active. Any targets
entering the zone will be automatically acquired.
When a target enters an acquisition zone, the buzzer sounds and "TT NEW TARGET"
or "AIS NEW TARGET" appears (in yellow-orange) in the Alert Box. The symbol of the
offending target is red and flashing. Further, the AIS display is automatically turned on
if it is off.
There are two types of acquisition zones available, arc and polygon, however, AZ1
can only be set as an arc.
Note: The acquisition zones are disabled when the setting for [2 AZ/ALR SELECT] in
the [ACQUISITION ZONE] menu is set to [TARGET ALARM ZONE].
