Steering Modes; Compass Steering Mode - NorthStar EXPLORER AP380 Installation And Operation Manual

7 Steering modes

Important:
• The AP380 cannot control the boat better than a helmsman. The AP380 is not intended for use in
extreme weather, in adverse conditions or near other boats, dangerous waters or land.
In these conditions, disengage the AP380 and steer manually.
• Never leave the helm unattended, keep a watch at all times and be ready to
resume steering the boat manually.
• Do not try to turn the rudder by hand when the AP380 is engaged.
• Local variations in magnetic field can affect the accuracy of the compass heading.
Such variations are the responsibility of the user.

7-1 Compass steering mode

The AP380 has three ways of steering the boat, compass, GPS and wind. To select an appropriate mode,
see section 3-7. In Compass mode, the AP380 steers the boat to a set course, called CTS (Course to steer).
