14 | Operation

parameters control the response of the boat at different

speeds or wind directions. The two parameter sets can be

automatically or manually selected, and each set can be

manually adjusted (response adjust).

The speed at which the autopilot automatically changes

from LO to HI parameters (or opposite) is determined by

the "Transition HI-LO" set in the Installation/

Commissioning/Seatrial menu, page 83. See diagram on

next page.

At no speed input the autopilot defaults to LO steering

parameters when engaging an automatic mode from

STBY. This is a safety feature to prevent oversteering.

Transition Speed set to 9 Knots

Transition to LO parameters

with increasing speed: 10 Knots

Power boats

On power bo

ats the automatic selection of HI or LO is

determined solely by the speed of the boat as shown in

the diagram above.

Sailboats

hen sailing in WIND mode, the parameter set is

determined by the speed of the boat and the direction of

the wind as per below.
