AutoTrim

You may also wish to adjust the AutoTrim setting. AutoTrim determines how quickly
the SPX-5 Tiller system applies 'standing helm' to correct for trim changes, caused,
for example, by changes in the wind load on the superstructure, or an imbalance of
engines.
Increasing the AutoTrim level reduces the time the SPX-5 Tiller system takes to get
back onto the correct course, but makes the boat less stable. If the SPX-5 Tiller
system:
• Gives unstable course keeping and the boat 'snakes' around the desired course,
decrease the AutoTrim level.
• Hangs off course for excessive periods of time, increase the AutoTrim level.

Adjusting

Before attempting to adjust the AutoTrim setting, ensure you have sufficient
experience using your SPX-5 Tiller system.
If you need to adjust AutoTrim, go up one level at a time and use the lowest acceptable
value. The range of settings is from OFF (no trim correction) to 4 (fastest trim
correction).
To adjust the AutoTrim:
1. Access the AUTOTRIM screen in Dealer calibration, then:
2. Use -1 or +1 to adjust the AutoTrim level.
3. Press and hold standby for 2 seconds to save the changes.
4. Press auto to check the SPX-5 Tiller system performance in Auto mode.
