• LO-A: Low response mode set automatically
• HI-M: High response mode set manually
• LO-M: Low response mode set manually
Ú Note:
If no speed input is available the autopilot defaults to LO
steering parameters when engaging an automatic mode. This is
a safety feature to prevent oversteering
Sea state filter (AC12N/AC42N)
This filter is used to reduce rudder activity and autopilot sensitivity
in rough weather.
• OFF: Sea state filter is disabled. This is the default setting.
• 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 sea state filter.
• MANUAL: Linked to the steering response control settings
described previously. It may be used to manually find the
optimum combination of course keeping and low rudder activity
in rough but steady sea conditions.

Ú Note:
Sailing parameters are only available when the boat type
is set to Sail.
• Tack time: Controls the rate of turn (tack time) when performing
a tack in wind mode.
• Tack angle: Controls the angle that the boat will tack to between
50º - 150º in AUTO mode
• Wind mode: Select what wind function the autopilot will use
when in wind mode
- Auto:
If AWA is ≤60º: Wind mode will use AWA
If AWA is >60º: Wind mode will use TWA
