(Rev. 1) Rotograph EVO 3-15
The "Centring/Patient Entrance" button
is used to:
-
start/stop the start examination
procedures
- bring the rotation arm to the
patient entrance position at the end
of the exam.
The "Examination Selection Mode"
takes place by means of three keys: the
first one, identified by the symbol "M"
helps select the exam mode between
Panoramic, TMJ, Sinus, and
Cephalometric.
The other two, identified by the arrows,
help navigate within the exams of each
mode.
It is possible to select the anatomic
mode examinations (anatomic
selection), using prefixed exposure
values.
This kind of selection enables to choose
between Adult/Child, each with three
different sizes (small, medium, large).
The Panoramic mode enables to select
the patient's type of biting between:
protruded, standard or retracted,
marked by the lighting up of one of the
three available LEDs.
The arch selection does not influence
the values of kV and mA but acts on
the position of the focus layer.
