Refer to the MSD50 manual for further information.

If you prefer to use the rudder angle display when leaving the
dock, proceed as follows:
After turn on the rudder angle display will alternate between 10
degrees port and starboard to indicate that the "rudder" zero point
need be set.
Use the wheel to bring the "rudder" to midship position. Turn the
wheel from lock to lock (H.O. to H.O.) and count the exact
number of turns. Then start from one lock position and turn the
half number of turns.
