Adjusting the sensitivity in monitoring the boat’s trim
The NAVpilot-511/520 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.

is calculated automatically depending on the ship’s length entered on the DOCK SIDE
SETUP menu.)
8. Press the course control knob to finish.
