2. Select display illumination level 0 (LAMP 0) on any other SeaTalk
instrument or autopilot control unit.
3. The tiller pilot should immediately respond by switching off its
display illumination. If the illumination does not switch off, there
is a cabling fault between the tiller pilot and the instruments or
control unit.
5.2 Initial sea trial
CAUTION:
Failure to carry out the sea trial may result in impaired autopilot
performance on some compass headings.
When you have checked that the system is operating correctly, you
must complete a short sea trial to calibrate the compass.
The tiller pilot has a built-in calibration capability so you can
fine-tune it to suit your boat, its steering system and its dynamic
steering characteristics.
As supplied from the factory, the autopilot is calibrated to provide
safe, stable control for most boats.
• Do not attempt to make any permanent changes to the
recommended calibration values until you have completed the
sea trial.
• You must carry out the initial sea trial in conditions of light wind
and calm water – so you can assess the autopilot’s performance
without the influence of strong winds or large waves.
