4.14 Setting an 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 the indication TT target in ACQ ZONE (or AIS
target in ACQ ZONE) appears (in yellow) 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.
