Adjusting the sensitivity in monitoring the boat’s trim

The NAVpilot-511/520/611 continually monitors the boat’s trim in order to keep the trim sensitivity optimum. A lower setting is common because boat’s trim usually does not change quickly. A large number changes the trim compensation value more frequently. Too high of a setting may result in the following problems.

•Trim sensitivity is over-affected, resulting that a trim appears in both port and starboard directions alternately.

•Trim compensation mechanism responds to the yawing, resulting in more serious oscillation of ship’s heading.

To set the auto trim sensitivity:

1.Rotate the course control knob to select AUTO TRIM from the PARAMETER SETUP menu.

2.Press the course control knob to show the auto trim options window.
