The Sea-trial menu can only be accessed if the Dockside Settings
are done and confirmed. It is also recommended that the
Interface Setup be performed prior to Seatrial settings.
The seatrial settings do the following:
• Rudder zero adjust (To tell the AP20 the precise midships
position of the rudder)
• Compass calibration (To automatically compensate for
onboard magnetic Deviation)
• Compass Offset (To offset the final compass heading readout)
• Automatic tuning (An optional method of determining the
steering parameters)
Advance through the IM until the following display is presented:
