3.3.6 Memorizing your boat's characteristics
The automatic tuning enables the Navpilot 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, if it is
difficult to perform this procedure due to limited space or time constraints, this procedure is
not necessary and the Navpilot will still fully learn all boat parameters over the course of the
first usage. It is not mandatory to perform this procedure as in some other autopilot
systems.
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.
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.
After the tuning, the indicator "?" next to "AUTO TUNING" on the SEA TRIAL menu changes
to "DONE".
3.3.7 Setting the rudder dead band
You can set the dead band of the rudder automatically or manually. The setting is normally
performed automatically during the RUDDER TEST. Manually setting parameter is normally
not recommended and may in fact be only useful on older vessels with chain driven or old
worn rudder system.
1. Rotate the course control knob to select "RUDDER DEAD BAND" from the SEA TRIAL
menu.
2. Press the course control knob to show the rudder dead band options window.
3. Rotate the course control knob to choose "AUTO" or "MAN".
AUTO: Use the rudder dead band automatically detected by the RUDDER TEST on the
DOCK SIDE SETUP menu.
MAN: You can enter the appropriate value. (Setting range: 0.1 to 5.0º)
4. Press the course control knob to return to the SEA TRIAL menu.
