The smaller wheel on the  handle  of the transducer controls the scan plane. The  transducer 
scan  plane  can  be  rotated  from  0°  (transversal  plane)  to  90° (longitudinal  plane)  to  180° 
(transversal plane, left/right inverted)  All planes in between  can also be chosen. This makes 
it possible to scan a conical imaging volume. The larger wheel on top of the handle is used to 
control  the  transducer  Anterior/Posterior  tip deflecti
on  (120°  +10°  up  and  90°  +10°  down). 
Both wheels have a friction lock and freely moving mode.
