CAUTION 
In setting an automatic acquisition zone, it is 
necessary to adjust the gain, sea clutter 
suppression and rain / snow clutter suppression 
to ensure that target echoes are displayed in the 
optimum conditions. No automatic acquisition 
zone alarms will be issued for targets undetected 
by the radar, and this may cause accidents such 
as collisions.

The automatic acquisition function sets a zone in a range and issues an alarm when a new target (which is not 
yet acquired) goes into this zone. 
For the setting of an automatic acquisition zone, refer to " Acquiring Target " in Section 5.2.1.
