PREPARATIONS FOR THE EXPOSURE
User's manual
6 PREPARATIONS FOR THE EXPOSURE
6.1 Switching the unit on
The on/off switch is located under the generator box.
When the unit is switched on it will carry out an auto-
matic self-test during which the Display CPU software
version is shown on the kV display, and the Tube head
CPU software version on the time display.
After the self-test is completed the default exposure
values will appear on the displays.
The default exposure values can be reprogrammed by
the user, see section 10.1 “Programming the default
exposure and density values” on page 19.
NOTE There are two sets of default exposure values: one for
the adult mode and the other for the child mode. The
unit is always in the adult mode when it is switched
on.
6.2 Selecting the cone
Select the cone to be used in the exposure. It is recom-
mended to use the long cone in order to keep the absor-
bed dose to the patient as low as possible.
Long 30 cm (12”)cone
The long cone is attached into its position by pushing it
into the short cone and rotating it so that the red point
on the short cone and the black point on the long cone
are in line.

NOTE The standard cone is suitable for the bisecting angle
technique, and the long cone is used for the parallel-
ing technique.
Bisecting angle technique
The patient holds the film or sensor in place with his
finger. The x-ray beam is directed perpendicularly to-
wards an imaginary line which bisects the angle bet-
ween the film plane and the long axis of the tooth.
Paralleling technique
The film or sensor is placed to a film holder which is
used to align the film parallel to the long axis of the
tooth.
