Target update frequency
The update frequency for AIS targets and Radar targets is defined in the Targets menus. The
frequency is set individually for AIS and Radar targets. From within these menus you can also
select to manually update the target information.
Lost target warnings
A warning is automatically triggered if an AIS target or Radar target is lost.
By default a lost target warning filter is enabled for both AIS and Radar targets. The filter will,
if enabled, only generate warnings for lost targets within a specified range. The filter is
intended to minimize the number of alerts presented to the user while still following general
guidelines for safety. The filter can be disabled by unchecking the checkbox. Settings for AIS
and Radar targets can be configured independently.
If any of the lost target warnings are turned off this will be indicated in the Indication panel.
