Guard Zone Alarm - JRC JMA-9832-SA Instruction Manual

...... Guard Zone Alarm

In setting a guard zone, it is necessary to adjust the radar tune, gain, sea clutter
suppression and rain/snow clutter suppression to ensure that target echoes are displayed
in the optimum conditions. The guard zone alarm is not generated against the targets that
are not detected by radar.
The guard zone functions are to set a zone at an arbitrary range and to deliver an alarm if any target
intrudes within this zone.
For the method of setting a guard zone, refer to section 3.4 "Set Guard Zones".
