Lost Target

Targets not detected in five consecutive scans become "lost targets". A lost target is
shown in the display with a flashing red "X". Flashing stops after lost target alert is ac-
knowledged.
If you are in an area where tracked targets are lost frequently, you may want to disable
the lost target alert against tracked targets, by maximum range or minimum speed.
