Automatic Deadband Control (Auto Seastate) - Raymarine ST1000+ Owner's Handbook Manual

12
You can revert to normal operation by pressing either -1 and +10 or +1 and -10
together again.

Automatic deadband control (Auto Seastate)

In Auto, WindTrim or Track modes, the tiller 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. From Auto, WindTrim or Track mode, press -1 and +1 together to switch from
AutoSeastate to Fixed Minimum Deadband.
2. The " ° " sign flashes when Fixed Minimum Deadband is selected. Minimum
deadband provides the tightest course keeping possible, at the expense of
increased power consumption and drive unit activity.
