In the ACQ AUTO mode, the targets within a guard zone will be acquired
automatically. The guard zone can be set arbitrarily. If a guard zone is not set,
a guard zone of 3 NM and ±45 degrees in the direction of the own ship will be set.
(Guard Zone 1: Heading direction, Guard Zone 2: Sternward direction)
For the setting method, refer to section 3.4 "Set Guard Zones."
Guard zone 1 will come on when GZ1 is clicked. When GZ1 is pressed again,
automatic tracking will turn off and the guard zone will be erased from the radar
screen, but other ships that were being tracked shall continue to be tracked.
