magnetic dip angle (for boats faster than 20 knots only)
All magnetic compasses are effected by ‘Northerly turning errors’ in the Northern Hemisphere or ‘Southerly turning errors’ in the Southern Hemisphere, which increase with boat speed and magnetic dip angle in higher latitudes. These can cause heading instability at boat speeds greater than 20 knots when steering with an autopilot. By entering the dip value indicated on the compensation chart, the autopilot will be able to correct for these errors and improve the heading stability. Use the minimum value necessary to stabilise the heading.

joystick control
The joystick is an optional device that allows direct control of the rudder. There are two joystick operating modes available to the helmsman:
Normal: the rudder moves in the direction of the joystick. When the joystick returns to the central position the rudder movement stops. The greater the movement of the joystick, the faster the response of the rudder.
Proportional: the position of the rudder follows the position of the joystick. When the joystick returns to the central position the rudder returns to its initial position.
Note: Until all parameters have been set or checked the autopilot should not be used to steer the boat.
