Autopilot | NSS Installation Manual
1. Find the bearing from the boat position to a visible object. Use a chart or a chart plotter
2. Steer the boat so that the center line of the boat is aligned with the bearing line pointing towards the
object
3. Change the o set parameter so that the bearing to the object and the compass readout becomes
equal. Refer graphic above
Note: Make sure that both the compass heading and the bearing to the object have the same
unit (°M or °T).
Setting the Transition speed (HI/LO)
This is the speed at which the system automatically changes from
LO to HI steering parameters.
On power boats it is recommended that you set a value that
represents the speed where the hull begins to plane or the speed
where you change from slow to cruising speed.
On sailboats the transition speed should be set to 3-4 knots to
give the best response in a tack.
Transition to LO parameters with
increasing speed: 10kn
Transition speed set to 9kn
Transition to HI parameters with
decreasing speed: 8kn
LO response
HI response
Active response parameter set is shown in the autopilot popup, and the following abbrevia-
tions are used:
HI-A High response parameters set automatically
LO-A Low response parameters set automatically
HI-M High response parameters set manually
LO-M Low response parameter set manually
Autotuning
The autotune feature will run the boat through several tests and then automatically set the
most important steering parameters.
Autotune is not required for the autopilot to function as it is preset with steering parameters
that should steer most boats in the 30-50 foot range.
You can manually set all parameters that are set during autotuning. Refer next page.
Seastate  lter
The Seastate  lter is used to reduce rudder activity and autopilot sensitivity in rough weather.
OFF Seastate  lter is disabled. This is default
AUTO Reduces rudder activity and autopilot sensitivity in rough weather by an
adaptive process. The AUTO setting is recommended if you want to use the
seastate  lter
MANUAL Linked to the steering response control settings described previously. It may
be used to manually  nd the optimum combination of course keeping and
low rudder activity in rough but steady sea conditions
