How to set the collision alert (CPA/TCPA alert)

This radar calculates CPA and TCPA
by using own ship and relative target
positions. An AIS dangerous target is
one whose CPA and TCPA are within
the range of the CPA and TCPA limits
set in the TT/AIS box. The AIS symbol
of an AIS dangerous target is red and
flashing, and is announced with the
Alert 536 "AIS CPA/TCPA". After the
alert is acknowledged the target sym-
bol is displayed in red color.

visual lookout for avoiding collisions,
whether or not the radar or other plotting
aid is in use.
