AUTOTUNE is a dynamic function that enables the autopilot
system to automatically set up the two main steering
parameters (Rudder, Counter Rudder) for the boat. The scaling
factors of the parameters are also set automatically as a function
of the boat type selection performed in the Dockside menu.
Note ! Autotune is an optional procedure that is not required for the autopilot
to function. The autopilot is preset with steering parameters that
should steer most boats in the 30 - 80 foot range and Autotune is not
needed if the preset parameters steer your boat satisfactory.
Recommended speed during Autotune varies with the type of
boat, but should not exceed 10 knots. Autotune should not be
performed at planing speed!
For displacement boats use a speed that is approximately half
the normal cruising speed (i.e. if cruising speed is 10 knots, do
the Autotune at about 5 knots).
The parameter values calculated during Autotune becomes the
LO speed parameters. The HI speed parameters are
automatically set to 66% of the LO.
If possible it is recommended to perform the Autotune steering
East or West, as this will yield the best balanced parameters.
WARNING ! The Autotune function will take control of the boat and
perform a number of S-turns. It must always be performed
in open waters with sufficient safe distance to other traffic.
The Autotune function may take from 1 to 2 minutes to
complete.
