NOTE
Position the patient's head so that the Frankfort plane
coincides with or, if you are unable to slide the light far
enough down, is parallel to the Frankfort plane light
beam. To do this support the back of the patient's
head with your hand and then adjust the tilt of the
patient's head by raising or lowering the vertical car-
riage with the height adjusting keys. The patient's back
should be straight. If necessary stretch and straighten
the patient's cervical vertebrae by moving the vertical
carriage up slightly.
Press and hold either of the focal trough positioning
keys to adjust the position of the patient positioning
mechanism until the focal trough light falls on the
region of the maxillary sinus that you wish to X-ray.
Press the ready key to drive the cassette carriage to
the ready position. The ready light will come on.
Ask the patient to swallow and stand as still as
possible. Move two meters (seven feet) from the unit.
Protect yourself from unnecessary radiation.
Press and hold down the exposure button on the
remote control for the duration of the exposure. At the
end of the exposure cycle the temple supports will
automatically open. The patient can then be guided
from the unit.
If the automatic cassette carriage return is ac-
tivated, see section "11.2 Automatic cassette
carriage return" on page 31, the rotating as-
sembly will return to the ready position before
the temple supports open.
Press the return key to drive the rotating assembly to
the ready position and the cassette carriage to the
loading position. This is not necessary if the cassette
carriage is set to return to the loading position auto-
matically.
Remove the cassette from the unit and process the
film.
