DEADBAND
A deadband in the rudder control loop is necessary to stabilize the
rudder and prevent it being over-active. It also will optimize the
adaptive rudder-loop function. The with of the DEADBAND can be
adjusted by using the INCREASE or DECREASE button. A narrow
deadband may cause the rudder to hunt, a broad deadband will
cause the pilot to steer poorly and "essing".

MIN RUDD.
Some vessels may have a tendency of not responding to a small
rudder deflection around midship position, due to
whirls/disturbance of the water-stream passing the rudder. This
function is particularly useful on water jet boats.
By setting the Min. Rudder to a certain value, the rudder will move to
the set rudder amount by one rudder command.
The amount of rudder decided by the p-factor (weather) and counter
rudder is added to the Min. Rudder, i.e.:
Min. Rudder
4°
P-fact./Counter Rudder 1°
Total rudder amount 5°
Additional rudder commands to the same side will not activate the
Min. Rudder. When the rudder is returning towards midship, it will
move in one step from the Min. Rudder value to the midship
position.
Maximum amount is ±10°
Range::
OFF - 10° in 0.5° steps
