Reference
•True: Regardless of the movement of your
vessel, the trail of other vessels displays a
real movement over ground. Therefore, a
stopped target's trail is not displayed. The
True trail requires a heading signal and
your own vessel's position information.
•Relative: The trail of other vessels is relative to
your vessel. In this mode, other vessels’
movement and your vessel’s movement
are combined, so, Relative trail is valid if
you want to look at the relative movement
to avoid collisions. However, a stopped
target’s trail is also displayed. In that
case, it is difficult to see in some places
such as near islands.
L
Regardless of this setting, the display acts as:
•The Relative trail setting when the Head-UP (H-UP)
screen is selected.
• The True trail setting when the True motion (TM)
screen is selected.
Time
Selects the trail time from 30 seconds, 1 minute, 3
minutes, 6 minutes, 15 minutes, or
∞ (continuous)
Color
Selects the trail time from Blue, Yellow, Green, Red,
Orange, and White.
Level
•Low: Leaves a trail between Low and High levels.
• Middle: Leaves a trail between Mid and High levels.
•High: Leaves a trail only at the High level.
