PROGRAMMING THE EXPOSURE VALUES
20 Prostyle Intra X-ray Unit
User's manual
The density value can now be changed with the parameter
adjustment keys. Note, that the density value will affect
the time value both in adult and in child mode.
In the normal mode the type of the film processor, proces-
sing chemicals and temperatures used will affect the film
density. The density has 11 steps from -5 (light exposures)
to +5 (dark exposures).
In the digital imaging mode the density has 10 steps from
-9 to 0.
Select the child/adult mode and program it settings as des-
cribed above or exit the programming mode by pressing
and holding down the select key. The density value is sto-
red in the memory.
NOTE If you interrupt programming for over 45 seconds, the
unit automatically exits the programming mode, and the
current values will be stored in the memory.
10.2 Programming the preprogrammed settings
NOTE Two sets of exposure values (time/kV) can be program-
med for each exposure region: one for adult mode and
one for child mode. When the indicator light is on, the
unit is in the child mode.
NOTE The exposure parameters - time and kV - are program-
med corresponding to the normal mode density value 0.
The time value will be automatically changed according
to the selected density value in both the normal and digi-
tal imaging mode when you exit the programming mode.
Select the exposure region with the preprogrammed set-
ting keys. Press the desired key once to select the projec-
tion of the maxilla, and press the key twice to select the
projection of the mandible. The indicator light of the se-
lected projection will come on.
The current time and kV values appear on the respective
displays.
