P4 – P9 Programs with Head Positioner
• For these exposures the head positioner must be
used (see page 24).
Using the ↑ and ↓ keys, adjust unit height so that ear
•
fixations and external auditory canals match up.
• Remove chin support and bite block.
• Move the chin support to the value indicated for the
respective mandibular joint exposure under "Expo-
sure Programs".
• Position the patient's head in the head positioner J.
Close the temple supports so that the ear fixations
are inserted in the external auditory canals.

before (Have the patient take a small step toward the
column).
• Swing out the mirror.
• Switch on the light localizer to set the correct posi-
tion. Press the key on the control panel.
• Clip contact spacer L onto the tube after head posi-
tioning and push downwards to support forehead.
