How to Ignore Slow Moving AIS Targets

The proximity AIS target alarm may often sound in areas of heavy vessel traffic. You
can prevent frequent release of the alarm against slow, non-threatening targets by
specifying the maximum target speed that triggers the alarm. Any target whose speed
is lower than set here does not trigger the alarm.
1. Open the Home screen, then tap [Settings]→[Targets].
2. Tap [Ignore Alarms for AIS Slower than...] to open the software keyboard.
3. Set a speed, then tap [ ]. Any AIS target whose speed is lower than set here is
ignored.
4. Tap the close button on the title bar to finish.

How to Display AIS Safety Messages

When you receive an AIS safety
message (addressed or broadcast)
from an AIS transponder equipped
vessel, the Status bar displays the
flashing message "New Text Tele-
gram(s)". Tap the Status bar to dis-
play the message. The AIS symbol
for the vessel that transmitted the
message is put at the center of the
screen and a pop-up window ap-
pears, showing the AIS safety relat-
ed message. You can delete the
message by tapping [Delete Message].
You can disable the AIS message notifications by turning off [AIS Message Notifica-
tion] in the [Targets] menu.
