3.3.6 Memorizing your boat’s characteristics
The automatic tuning enables the NAVpilot-500/511 system to automatically set up the two
main steering parameters (rudder gain and counter rudder gain) for the boat.
This procedure will shorten the learning time for the self-learning feature. However, as
parameters are memorized over time, it is not necessary to complete the procedure.
Do the following procedure in calm water.
1. Confirm that you have enough open water around you, and then run the boat straightly
between 10 and 12 knots straight to windward.
2. Rotate the course control knob to select “AUTO TUNING” from the SEA TRIAL menu.
3. Press the course control knob to show the auto tuning options window.
YES
NO
Auto tuning options window
4. Rotate the course control knob to select “YES”.
5. Press the course control knob to start the auto tuning.
The boat runs in the AUTO mode. While tuning, the message “AUTO TUNIG – WAIT (**%)
appears. When the auto tuning is completed, the message “AUTO TUNING IS
COMPLETED” appears. (This tuning takes approx. 5 minutes.)
6. Press any key to finish.
