3.
Select Settings, Network, Device list, and select the compass
from the list.
4.
Select Configure.
5.
Change the offset parameter so that the bearing to the object
and the compass readout becomes equal.
Ú 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
Ú Note: NAC-1 uses the Steering response parameter to adjust
rudder activity. See description later in this section.
The transition speed is the speed at which the system automatically
changes between LO and HI steering profiles.
The steering profiles are used to accommodate the boats' tendency
to exhibit different steering characteristics at different speeds. You
may also have different preferences about the steering performance
of your boat required at low and high speeds.
On power boats it is recommended that you set a value that
represents the speed where the hull begins to plane, the speed
where the boat's steering characteristics change, or at the speed
you want the autopilot to change behavior.
On sailboats the transition speed should be set to around 3-4 knots
to give the best response in a tack.
There is a 2 knots hysteresis to prevent oscillation of HI/LO steering
parameters when the vessel is travelling at the transition speed.
Example
The transition speed is set to 9 knots.
• The system changes from LO profile to HI profile when the speed
increases to 10 knots (= Transition speed plus 1 knot)
• The system changes from HI profile to LO profile when the speed
decreases to 8 knots (= Transition speed minus 1 knot)
The active response parameter set is shown in the autopilot popup
and the following abbreviations are used:
HI-A High response parameters set automatically
LO-A Low response parameters set automatically
HI-M High response parameters set manually
