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.

3.Rotate the course control knob to select “ON”.

4.Press the course control knob.

5.Rotate the course control knob to select current value.

6.Press the course control knob and the current value is circumscribed with a double rectangle.

7.Rotate the course control knob to set value (Setting range: 1 to 100, the default setting is calculated automatically depending on the ship’s length entered on the DOCK SIDE SETUP menu.)

8.Press the course control knob to finish.
