Chapter 2: Basic Operation 92 Basic OperationAdjusting performance – Types 150/400 and 100/300To adjust the performance of Type 150/400 (non-GyroPlus) andType 100/300 autopilot systems you can change the response level.Response level – Types 150/400 and 100/300The response level controls the relationship between the autopilot’scourse keeping accuracy and the amount of helm/drive activity.You can adjust the default response level in either User or DealerCalibration (see page 89). This determines the default power-upresponse level.However, when using your autopilot on a day-to-day basis, you willneed to make temporary adjustments to the response level. By doingthis you can match autopilot performance to different conditions.Type 150/400 (without GyroPlus) and Type 100/300 autopilotsystems have three different response levels:• Response Level 1: AutoSeastate on (Automatic deadband)This setting causes the autopilot to gradually ignore repetitiveboat movements and only react to true variations in course. Thisprovides the best compromise between power consumption andcourse keeping accuracy, and is the default calibration setting.• Response Level 2: AutoSeastate off (Minimum deadband)This setting provides tighter course keeping. However, thisresults in increased power consumption and drive unit activity.• Response Level 3: AutoSeastate off + yaw dampingThis setting provides the tightest possible course keeping byintroducing counter rudder yaw damping. You can adjust thecounter rudder setting in Dealer Calibration (see page 95)To make a temporary change to the response setting:1. Display the RESPONSE screen by pressing either the resp key orthe -1 and +1 keys together momentarily.2. Press -1 or +1 or the up arrow or down arrow keys to change theresponse between levels 1 to 3.3. Press disp or wait for 5 seconds to return to the previous display.Note: You will lose these temporary changes to response levelwhenever the system is powered off. You can make permanentadjustments in User or Dealer Calibration (see page 89).
