If gyrocompass has been selected, you can also turn off and on again and adjust the autopilot as described in “Parameter setting”, page
The range for the Off Course limit is ±5 to ±32 degrees in one degree step from set course. Alarm is given if the difference between set course and compass heading exceeds the limit. See “Fault warnings”, page

Specification of vessel's length determines the values for autotrim, counter rudder time constant, turn initiate and turn rate. The values are based on experience realising, however, that not only the length contributes to the steering characteristics of a vessel. In some occasions, a selected length bigger or smaller than the one of a particular vessel, may give a better result.
