How to filter AIS targets

1. Right-click [AIS] on the [TT/AIS] page in the [NAV Tools/Overlay box], select [Set-
ting] and open the [Setting.1] page.
(The [Setting.1] page can also be opened from the menu (MENU→[TT/
AIS]→[Setting]→[Setting.1].)
2. In the [AIS DISP Filter] window, set each item referring to the description below.
• Click the button of [Class A], [Class B] and [Base Station] to show [OFF] or [ON]
to hide or show those targets.
• Set the maximum range with [Max Range]. Any target beyond the range set
here will not be displayed.
• Set the ship speed for AIS targets, with [Min Ship Speed]. Any AIS target whose
speed is lower than that set here will not be displayed.
3. Click the [Save] button to save settings. Click the [Close] button to close the dialog
box.
Note: AIS and tracked target viewing limitations are as follows:
• AIS and tracked targets are displayed on top of chart 1:1,000,001 for S57
charts.
• AIS and tracked targets are displayed on top of chart 1:1,900,001 for ARCS
charts. This allows display of AIS and tracked targets on top of the largest scale
ocean charts (original scale 1:3,500,000) when they are zoomed to "overscale".
