4.2 How to Select the AIS Display Mode
• [DISP OFF]: AIS symbols are hidden.
• [DISP FILT]: Only filtered AIS targets are displayed.
• [DISP ALL]: All AIS symbols are displayed.
To disable the AIS function, put the cursor on the AIS display mode indication, then
long right-click. The AIS display mode indication shows [FUNC OFF] when the AIS
function is disabled.
Note: The AIS mode indication is hidden when [SIMPLE] display mode is used. To
change AIS settings in [SIMPLE] mode, first restore [NORMAL] display mode, adjust
the settings, then return to [SIMPLE] mode. See section 1.9 for how to change the dis-
play mode.
4.3 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 "TT/AIS
symbols" on page AP-34.
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.
When the AIS function is active: Above message is prioritized as a Warning level
alert.
