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, as explained in
the description of the following steering modes.
Standby mode
Standby (STBY) mode is used when you steer the boat at the helm.
• Switch the autopilot to STBY mode from any operation by a short press on the STBY/
AUTO key.
Non-Follow Up (NFU, Power steering)
In NFU mode you use the port and starboard arrow buttons in the autopilot pop-up to
control the rudder. The rudder will move as long as the button is pressed.
• Activate NFU mode by selecting the port or starboard arrow button in the pop-up when
the autopilot is in STBY or FU mode.
You return to STBY mode by a short press on the STBY/AUTO key.
Follow-up steering (FU)
In FU mode you use the rotary knob to control the rudder angle. Press the rotary knob, then
turn the knob to set the rudder angle. The rudder moves to the commanded angle and then
stop.
• You select FU mode from the autopilot pop-up
Ú
Note: If the autopilot pop-up is closed or if an alarm dialog is activated on the unit
controlling the autopilot in FU mode, the autopilot automatically changes to STBY mode.
Warning: While in FU mode you cannot take manual control of the wheel.
AUTO mode (auto compass)
In AUTO mode the autopilot issues rudder commands required to steer the vessel
automatically on a set heading.
• You select AUTO mode from the autopilot pop-up. When the mode is activated, the
autopilot selects the current boat heading as the set heading.
Changing set heading in AUTO mode
You adjust the set heading by using the rotary knob, the Port/Starboard arrow buttons in the
autopilot pop-up, or by selecting the Heading tile in the autopilot pop-up and then entering
the desired heading value.
An immediate heading change takes place. The new heading is maintained until a new
heading is set.
Heading capture
When the vessel is turning in AUTO mode, an instant reset of the mode activates the heading
capture function. This automatically cancels the turn, and the vessel continues on the
heading read from the compass the very moment you re-activated the mode.
Tacking in AUTO mode
Ú
Note: The tack function is only available when the system is set up for boat type SAIL in
the Autopilot Commissioning dialog and is not available for NAC-1 autopilot computers.
