4. Scroll to select the Hard Over time option then
press
OK
to display the Hard Over time page.
5. Measure the time it takes for the autopilot to
drive the rudder from hard over port, to hard
over starboard.
6. On the Hard over time page, scroll to set the
appropriate time in the edit box.
7. Press
OK

End of autopilot dockside setup
At the end of the autopilot dockside setup, use the
CANCEL
button to return to a Pilot
Controller operational page. Before starting any sea trial or other open water
calibration, carry out the
Transducer setup and Miscellaneous setup procedures
(below).
Transducer setup
CAUTION:
Before starting any dockside setup procedure, ensure the boat is securely
moored alongside.
Use these dockside setup procedures to set:
•
Correct depth offset and sea temperature.
• Required method for calculating ground wind.
• Correct magnetic variation.
• Required display response.
• Trim tab calibration.
Introduction to transducer setup
Depth, speed and temperature data are derived from transducers in the boat’s hull.
Either of the following transducer configurations may be fitted to provide this data:
•
Conventional transducers, i.e. separate Depth and Speed, with the water temper-
ature sensor built into the Speed transducer
• Smart transducers (either combined Depth/Speed/Temperature (DST) or com-
bined Depth/Temperature (DT) transducers).
A Wind transducer may also be fitted, to provide wind speed and direction
information.
Depth offset and sea temperature must be calibrated as part of the Dockside setup,
but the exact method for calibrating these parameters depends on which transducers
are fitted:
•
With conventional transducers, the Depth offset and water temperature are cali-
brated separately.
• With a smart transducer, the depth offset and water temperature setup are part of
one continuous procedure.
The speed and wind functions are calibrated later as part of the Open water
calibration.
