Automatic deadband control (Auto Seastate)

The wheel pilot is set to AutoSeastate (automatic deadband control)
as a default. This causes the pilot to gradually ignore repetitive
movements of the boat and respond only to true course variations.
By preventing unnecessary rudder movement, AutoSeastate
provides the best compromise between power consumption and
course keeping accuracy.
If you want to switch off the AutoSeastate feature:
1. With the pilot in Auto mode, press -1 and +1 together to switch
2. The " ° " sign flashes when Fixed Minimum Deadband is selected.
From Auto mode
To switch back to AutoSeastate, press -1 and +1 again.
Note: The autopilot reverts to Automatic Deadband Control each
time you select Standby mode.
Operating hints – trim changes
CAUTION:
Only make major course changes when steering MANUALLY.
This ensures that the boat will safely clear any obstructions or
other boats, and you can take into account the changed wind and
sea conditions on the new heading before engaging the autopilot.
Large course changes which change the apparent wind direction can
produce large trim changes. When a sudden trim change occurs (for
example due to weather helm or sail imbalance) there will be a delay
of up to one minute before the automatic trim applies rudder to restore
the locked heading.

from AutoSeastate to Fixed Minimum Deadband (1°).
Minimum deadband provides the tightest course keeping
possible, at the expense of increased power consumption and
drive unit activity.
