How to read the XTE indication
The black boat-shaped mark shows own
boat’s movement and direction, and the
amount to steer to return to course. Using
the figure shown on the previous page as an
example, you would steer right by 000.02
nautical miles to return to course. When this
mark is out of range of the XTE scale, the
mark color changes from black to yellow.
The range of the XTE scale can be set as
shown below.

2.9 Highway Display
The highway display provides a graphic
presentation of ship’s course. It is useful for
monitoring XTE - the XTE scale shows
direction and amount in nautical miles to
steer to return to course. In the figure below,
for example, you would steer right by 0.02
nm to return to course.
Press the [XTE/HIWAY] key once or twice to
show the highway display.
