Autopilot modes
The autopilot has several steering modes. The number of modes and features within the
mode depend on the autopilot computer, the boat type and available inputs.
External system selector
An external switch can be used for controlling change over from manual to automatic
steering.
The mode descriptions in the following pages assumes that an external system selector has
opened for autopilot operation, or that no external selector is installed.
Hand steering
Standby mode
Standby mode is used when you steer the boat at the helm.
• Switch to Standby mode by pressing the STBY key.
Ú
Note: If sensor data vital for autopilot operation (e.g. rudder response) is lost when the
autopilot is running in an automatic mode, the system will automatically switch to
Standby mode.
Non-Follow Up (NFU) mode
In NFU mode you can use the port and starboard keys on the controller to operate the
rudder. The rudder will move as long as the key is pressed.
• Switch to NFU mode by pressing one of the port or starboard keys when the autopilot is
in Standby mode or FU mode.
Follow-up (FU) mode
In FU mode you turn the rotary knob to adjust the set rudder angle.
The rudder will move to the commanded angle and then stop.
• Switch to FU mode from Standby mode or NFU mode by pressing and holding the rotary
knob.
Quick menus in STBY, FU and NFU mode
From the Quick menu in Standby, NFU and FU you can change sources used for steering,
display active alerts and set manual speed.
Automatic modes
This autopilot system includes two automatic modes:
• Auto compass mode keeps the vessel on set heading
• NoDrift mode combines heading and position information, and keeps the vessel on a
straight track
You toggle between Auto and NoDrift mode by repeated presses on the Auto key. The
selection times out and triggers the mode shift. You can also confirm your selection by
pressing the Starboard key or the rotary knob.
