5.1 Initial Sea Trials
Initial sea trials should be carried out in calm conditions with plenty of sea
room. As the vessel will be constantly changing heading, it is most
important to maintain a constant look out.
Before sea trials:
• Read the Operating section of this manual.
• Carry out the system test to verify that the autopilot is operating
correctly.
5.2 Automatic Compass Heading Alignment and Deviation Correction
The displayed compass heading requires alignment with the ships
compass. Until this procedure is carried out, the autopilot compass

conditions preferably in flat water.
To select compass heading alignment and correction, push and hold
