This conservespower, but may compromise short-term course-keeping accuracy.Levels 4 to 6 should give good course keeping with crisp, well con-trolled turns under normal operating conditionsLevels 7 to 9 give the tightest course keeping and greatest rudderactivity (and power consumption). This can lead to a rough passagein open waters as the SPX-5R Drive system may ‘fight’ the sea.WARNING: Dealer calibrationChanging the Dealer calibration values can have a significantaffect on the SPX-5R Drive system steering characteristics andtherefore on the safety of your boat.Screen text OptionsCAL LOCK OFF Calibration lock off – Seatrial calibration can be accessed (default)CAL LOCK ON Calibration lock on – Seatrial calibration cannot be accessed
