Orientation of the hull unit
As a general recommendation, the hull unit shall be oriented with the hoist/lower motor pointing aft. If this orientation makes it difficult to access the Motor Control Unit, the hull unit may be rotated during its installation to the most suitable direction.

The physical distance between the Transceiver Unit and the hull unit is limited by the length of the transducer cables.
Note
Irrespective of the physical hull unit orientation, the transducer shall not be mechanically aligned. Hull unit alignment is done in the CS90 software by rotating the echo presentation in the display view.
