2.3 Adjusting autopilot performance
During normal autopilot operation in any mode you can make
temporary adjustments to:
• response level
• rudder gain
Note: You will lose these temporary changes to response level and
rudder gain whenever the system is powered off then on again. You
can make permanent adjustments in Dealer setup (see page 108).
Changing the response level (AutoSeastate)
The response level controls the relationship between the autopilot’s
course keeping accuracy and the amount of helm/drive activity.
• Response Level 1: AutoSeastate on (Automatic deadband)
This setting causes the autopilot to gradually ignore repetitive
boat movements and only react to true variations in course. This
provides the best compromise between power consumption and
course keeping accuracy, and is the default calibration setting.
• Response Level 2: AutoSeastate off (Minimum deadband)
This setting provides the tightest course keeping possible.
However, tighter course keeping results in increased power
consumption and drive unit activity.
To make a temporary change to the response setting:
1. Display the RESPONSE screen by pressing the -1 and +1 keys
together momentarily.
