Put the face bow on the patient's head, whereby the gla-
bella support is placed on the glabella and the side arms
rest above the ears.
The restraining strap is placed parallel to the side arms
and fastened. Now, the face bow should hold firmly on
the head without further support.
Pay attention that the side arms lie above the ears. The face bow must not be pulled down-
wards, on the pinna, or upwards by the restraining band.
Fixate the flag adapters of the extension set with the re-
spective screws on the side arms.
The porus knobs are inserted into both ear canals
through the holes of the flag adapters.
