Panorama Exposures
Chin Rest Positioning
1. <Initial Patient Positioning>
Put an X-ray protection apron on the patient. Have the
patient perform the incisal occlusion while biting on an
unused mouthpiece.
Line up the center of the mouthpiece with the center of the
upper and lower incisors.
Have the patient stand in front of the chin rest. Look at him
from the side, and have him pull in his chin and straighten
his back. Then look from behind and make sure his
shoulders and back are straight.
A new, uncontaminated mouthpiece must be used for
each patient to prevent from cross-contamination.
Do not use anything other than the special mouthpieces
provided.
* Keep mouthpieces in a clean, uncontaminated area.
2. Use the Lift Up or Down Key to raise or lower the chin rest
and line it up with the patient’s chin. Release the key when
the chin rest is at the right height.
The Lift has a Slow Start and Slow Stop. It will stop
automatically if there is an excessive load on it.
Usage Note
♦ Always use the Up and Down Keys to move the Lift. Never
try to force it; this would damage it.
♦ The over current protection circuit could be activated after
3 seconds for reasons such as an excessive load or the
failure to insert the cassette. The lift will stop and an
audible signal will sound. The unit will stop working and
one of the following messages will appear in the display
on the frame:
LIFT OVERLOAD! PROTECTOR ACTIVE
LIFT OVERTIME! PROTECTOR ACTIVE
To restore normal working order, press any one of the
occlusal type keys underneath the display on the patient
frame.
Line up the center of the mouthpiece
with the center of the upper and
lower incisors.
