The course maintained by the AP380 is controlled by the GPS device that is navigating to a waypoint. To
change course in GPS mode, select a different waypoint on the GPS device.
Tip

mode. For example it is helpful
to use Compass mode to control the boat when
setting up a GPS route, then change directly to
GPS mode.
Note for sailing boats:
•
The AP380 is not recommended for use in
light, changeable or gusty winds.
•
Take care when running downwind to avoid
an accidental gybe.
•
Wind mode requires the wind instrument to
be accurately calibrated.

To select GPS mode, the AP380 must be
receiving data from a compatible GPS instrument,
otherwise the GPS selection will not be available.
To engage the AP380 in GPS mode, the GPS must
be navigating to a waypoint or along a route;
otherwise the Explorer AP380 will display an error
message. If the boat is too far from the plotted
course, the Explorer AP380 will display a warning
message.
To select Wind mode, the AP380 must be
receiving data from a compatible wind
instrument, otherwise the Wind selection will not
be available.
