Note ! The information in section 2.3 only applies if your autopilot is
driving a Simrad MSD50 Stern Drive.
The MSD50 Stern drive unit has a relative feedback signal which
needs a zero point setting after the autopilot has been turned on.
Refer to the MSD50 manual for further information.
Zero point setting
Note ! If you do not need a rudder angle display when leaving the dock,
just steer the boat manually on a straight course and press the
AUTO button. The zero point is then set automatically.

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.
