AIS Symbols and Their Meanings
When the AIS display is active, each AIS target is marked with a symbol that indicates
the target’s status. For the meaning of each AIS symbol, see "AIS
symbols" on page AP-30.
Note 1:
The equipment continues to process AIS targets when the AIS feature is de-
activated. When the AIS is activated again, symbols are immediately displayed.
Note 2:
AIS symbols are momentarily erased and the screen is redrawn after the
heading is changed in the HEAD UP mode.
Note 3:
When no AIS data is received, the message "AIS COM ERROR" appears in
the Alert Box. Check connection with the AIS transponder.
When the AIS function is disabled
: Above message is prioritized as a Caution level
alert for IMO/R-types. A/B/W-types do not show this alert.
When the AIS function is active
: Above message is prioritized as a Warning level
alert for all radar types.

How to Use the AIS Display Filter
If there are too many AIS targets on the screen you may wish to remove unnecessary
ones. You can remove sleeping targets class A/B by distance from own ship, speed
and class. For example, you might want to remove slow moving targets, as they nor-
mally do not require close monitoring.
1. Open the menu.
2. Select [5 TT•AIS].
3. Select [5 AIS].
Note:
You can also right-click the AIS indication in the [TT•AIS] box to open the
[TT] menu.
4. Select [0 NEXT] to show the next menu page.
