You must have CPA ALARM set to ON in the ALARMS menu. If set to
OFF, there will be no CPA alarms regardless of the above settings.
TCPA
Set the Time to Closest Point of Approach (TCPA) interval. TCPA is the

SOG, COG and HDG if available.
Additional Vessel data will be transmitted once these details are
completed.
