98 ST4000+ Wheel & Tiller Autopilots: Owner’s Handbook
6 Setting-up the ST4000+
6.4 Autopilot calibration techniques
The autopilot’s factory default settings will provide adequate steering
for most boats. If you still experience problems with autopilot
performance after completing the Post Installation Procedures,
follow these six steps to optimize the setup for your boat.
Step 1 - Switch on ancillary equipment
Make sure you have switched on any ancillary equipment, such as a
GPS providing speed over ground (SOG) and latitude (LAT) data, or
a speed log providing speed through the water. This information will
help the autopilot provide its best performance.
Step 2 - Apply initial settings
Enter the Dealer setup mode (see page 106) and apply the following
initial settings.
