Cancelling Tracked Targets
Tracked targets can be cancelled individually or collectively. When a target
is cancelled all alerts relating to the target are automatically cleared. If
local tracked targets are being displayed then the tracked target is
cancelled on the current node only.
On a multi-node system a target that has been tracked on a Radar node,
and is cancelled on the Radar node, will also be cancelled on an ECDIS
node, see Tracking Targets, `Cancelling Tracked Targets on a Multi-node
System'.
To cancel an individual tracked target, do the following:
1. Position the cursor over the target and
right click. A semi-transparent window
appears next to the selected target with
Cancel Target in highlight.
2. Left click on Cancel Target . The
selected target is removed from the
video circle and all details relating to the
target in the Target Data window are
removed.
To cancel all tracked targets do the following:
1. From the Target Display window click
on the Cancel All Targets button. The
screen prompts to confirm cancellation
of all tracked targets.
2. Select OK to proceed with the cancellation. All tracked targets, with
the exception of an echo reference target, are dropped and
removed from the screen. If an echo reference target is selected a
prompt will be displayed to indicate that the echo reference target
may not be cancelled.
When Cancel All Targets is selected all AIS targets are set to sleeping
unless they meet the following criteria:

They are in an auto acquisition zone;

They are infringing the CPA/TCPA or Bow Crossing limits.
