SLOW WARN
The AIS unit calculated COG (Course Over Ground)
data of a vessel that is at anchor or drifting is unre-
liable, and therefore the CPA (Closest Point of Ap-
proach) and TCPA (Time to CPA) data may not be
correctly calculated. If a vessel is anchored in your
alarm zone, the unreliable data can cause the colli-
sion alarm to sound many times, even if there is no
real danger. To prevent this, when the anchored ves-
sel’s SOG (Speed Over Ground) is less than this set
value, the Slow Warn function assumes that vessel’s
COG is fixed towards your vessel and an alarm will
sound.
• OFF:
Turn OFF the Slow Warn function.
• 0.1 to 4.9 KT: Select the vessel’s speed.
