When the parameter value on the kV or mA display is not
flashing, the exposure time value can be changed with the
parameter adjusting keys.
NOTE
After adjusting the kV or mA value the unit will return
automatically to the time adjustment mode after 5 seconds
time.
Ask the patient to sit down. Place a protective lead apron
over the patient's chest.
The sensor is placed to a sensor holder which is used to
align the sensor parallel to the long axis of the tooth.
Use a long cone for the paralleling technique.
The patient holds the sensor in place with his finger. The
X-ray beam is directed perpendicularly towards an
imaginary line which bisects the angle between the
sensor plane and the long axis of the tooth.
