3D EXPOSURE IN "LARGE VIEW 2 VERTICAL"
The X-ray unit must be moved up before you can take the
second exposure. Press the up button until the chin
support is positioned under the patient's nose.
Now take the second exposure as described in section
12.4 "Taking an exposure" on page 60.
NOTE Keep the patient in the same position for both
exposures. Move only the unit, not the patient.
