How to Ignore AIS Targets

In the default setting, all AIS targets within 12 nm from your vessel are shown on the
display. When the screen becomes full of AIS targets, you can remove some of the
targets if you indicate a different display range.
Slow-moving targets within the AIS proximity alarm range cause frequent violation of
the AIS proximity alarm. You can prevent this frequent violation if you ignore targets
within the alarm range that are slower than the value you set.
1. Press the MENU key to open the menu.
2. Open the [Targets] menu.
3. Use the RotoKey to select [Ignore AIS Targets Farther Than.... ].This item re-
moves the targets that are at a distance greater than the value you set here.
4. Use the RotoKey to select a range.
5. Select [Ignore AIS Targets Slower Than....]. This item prevents frequent violation
of the AIS proximity alarm against AIS targets that are slower than the value set
here.
6. Use the RotoKey to set a speed. The setting range is 0.0 - 9.9 (knots).
7. Press the MENU key to close the menu.
