It is advisable that the offset value is checked after the Compass
Swing has been completed. Refer to Setting the Heading Offset to
review the procedure in full.

3.4.8 Calibration of Speed Input (S CAL)
The ACP Computer Unit can take a direct speed input from a
Paddle Wheel with a hall-effect output. Normally the autopilot uses
boat speed supplied via the Fastnet cable from the Instrument
System, this facility is only used when the installation does not
include an H-range Instrument System.
