Initial sea trial
When you have checked that the system is functioning correctly, you
must complete the setup by taking the boat on a short sea trial to:
• correct the compass deviation
• adjust the heading alignment
• check autopilot operation
• adjust the rudder gain
Note: Refer to your pilot controller instructions for important
setup and commissioning procedures.
The system has built-in calibration so you can fine tune it
to suit your boat, its steering system and its dynamic steering
characteristics. So you can perform the initial sea trial, we calibrate
the unit at the factory to provide safe and stable autopilot control for
the majority of boats.
You should perform the initial sea trial:
• when you have successfully completed all of the installation,
functional tests and rudder sensor checks
• before making any other changes to default calibration settings.
• in conditions of light wind and calm water, so you can assess
autopilot performance without the influence of strong winds or
large waves
• in waters that are clear of any obstructions
Note: You can return to hand steering at any time during the sea
trial by disengaging the wheel drive clutch, or removing the tiller
drive pushrod from the tiller pin.
EMC conformance
Always check the installation before going to sea to make sure that it
is not affected by radio transmissions, engine starting etc.
