Furuno MFD8 Installation Manual page 61

c) Motion Sensor and Motion Sensor Antenna Position:
If a Furuno satellite compass SC-30 or SC-50/110 is connected, set the distance
between antenna unit (or sensor) of the satellite compass and transducer (high
frequency and low frequency) at the "Motion Sensor Antenna Position" pull-down
menus.
Note: If a dual frequency transducer is used, the value for High and Low will be
the same.
When entering the value, the point of origin is the antenna of the satellite
compass.
Bow-stern: Set the distance from the satellite compass antenna unit to the
sounder transducer (HF and LF). The value is positive when going toward
the bow.
Up-down: Set the distance from the transducer to the antenna unit in the
vertical direction (this value is always positive)
Port-starboard: Set the distance from the satellite compass antenna unit to
the sounder (HF and LF). The value is positive when going starboard.
