Ais Symbols - Furuno FMD-3200 Operator's Manual

14. AIS TARGET FUNCTIONS
There can be several hundreds or several thousands AIS targets, and of those only a
few will be significant for your ship. To remove unnecessary AIS targets from the EC-
DIS display, the feature "active and sleeping AIS targets" is available. Initially any new
AIS target received by an AIS transponder is not-active (="sleeping"). Such non-active
targets are shown with a small triangle. The operator can pick any AIS target and
change it from non-active to active. Active AIS targets are shown with a large triangle
with speed vector, headline, rot indicator, etc. Further, the operator can pick active AIS
targets and change their status to non-active.
The feature "active and sleeping AIS targets" is very effective for focusing on only
those AIS targets which need supervision.
