display and sound until it is reduced to less than
0.3Nm.
Caution: Cross track error
correction
When returning to TRACK mode the
autopilot will correct the XTE in order
to keep to the defined track leg. The
direction of turn may not coincide with the
bearing to waypoint and may be different
from that expected.
Route completion
The autopilot displays the Route Complete warning
when you have reached the last waypoint on a route.

9.5 Wind vane mode (Sailing boats
only)
When the autopilot is in Wind Vane mode it uses the
wind angle as the primary heading reference. As
changes in the true or apparent wind angle occur, it
adjusts the locked heading to maintain the original
wind angle.

5 Vessel turns to maintain same relative
wind angle
You can only select Wind Vane mode if your
autopilot is receiving suitable SeaTalk, SeaTalk
NMEA 2000 wind direction data.
Autopilots can maintain a course relative to either an
Apparent or True wind angle. The default setting is
Apparent wind. If required, you can change this to
True wind from the Wind Type menu.
Using wind vane mode
You can select Wind vane mode from either
STANDBY or AUTO mode:
1. Steady the vessel onto the required wind angle.
2. Select Wind vane mode:
i. Wind vane mode can be selected by pressing
the Auto and Standby buttons together, or
ii. selecting Wind vane mode from the modes
menu: Menu > Mode > Wind vane.
This will enable Wind vane mode and lock the
current wind angle. The display shows the locked
heading (e.g. 128°) and the wind angle (e.g.
WIND 145P indicates a wind angle of 145° to
port).
3. The autopilot will then adjust the vessel's heading
to maintain the locked wind angle.
Adjusting the locked wind angle
1. You can adjust the locked wind angle by using
the -1, +1, -10 and +10 buttons, or the ROTARY
controller to change course. For example, to bear
away by 10° when the boat is on a starboard tack:
i. press -10 to turn the boat 10° to port – the
locked wind angle and locked heading will
both change by 10°.
