Automatic Exposure Selection AES (ABV)

i
NOTE
Only with the P1 exposure program.
After this button is pressed, the LED above the AES but-
ton lights up. The LED above the left patient symbol
lights up simultaneously. The programmed kV/mA value
is displayed.
Now press the corresponding patient symbol button
– for edentulous patients press the symbol which is one
size smaller than the patient.
After the exposure is actuated, the system automatically
determines the optimal kV/mA matched exposure val-
ues, based on the structure of the patient's head.
These data are digitally displayed subsequent to the
exposure.
After changing the cassette, the LED above the left
patient symbol automatically lights up again.
CAUTION
Before using a different type of film and/or intensifying
screen, the exposure parameters must first be adjusted
by an authorized technician.

NOTE
If the patient's cervical vertebrae could not be brought in-
to a stretched position (see page 28), we recommend
not to use the Automatic Exposure Selection AES
(possible overexposure) and to proceed as follows.

Select Exposure Data

• Select Exposure Data by tapping one of the four pa-
tient symbol buttons.
The LED above the button will then light up, and the
respective kV/mA matched pair will appear on the digital
display.
Manually, the exposure data can be modified with the –
+ buttons.
The mA values are automatically matched to the kV val-
ues. (See chapter "Program Values").
The kV/mA matched values for the patient symbol but-
tons are factory programmed.
Should you need to modify these values, see the chapter
entitled "Programming".
