Film Speed Adjustment
The general dose requirements for your specific x-ray system may differ depending on the
speed of the film used, and on other factors (e.g. different cone length, or added filtration),
therefore you may need to change the pre-set exposure time scale by a coefficient. This is
done through the Film Speed Adjustment procedure:
Keep key P pressed at power on. The relevant lamp flashes, "FSA" is displayed for 2 s, after
that the display shows the speed film coefficient (1 by default). Lamp P is flashing.
Using the s+ and s- keys, you may change the speed coefficient of the time scale as follows
(according to the R10 scale). The entire time scale is altered by shifting all nominal time
values by the given number of steps.
Coefficient
Nr of steps
Recommended film speed coefficient is 1 for D type films (Kodak Ultra Speed), 0.5 for E type
films (Kodak Ektaspeed Plus, Agfa Dentus M2
Insight).
Press key P to confirm the selected speed coefficient, and to exit the Film Speed Adjustment
modality and enter the Time Scale Customization modality.
Time Scale Customization
Using this function it is possible to customize exposure times for each tooth/technique,
(independently and separately for tubehead
After the Film Speed Adjustment modality, the Time Scale Customization mode is initiated.
The message TSC is displayed for 2 s and the lamp P lights on.
Select the tubehead of interest by the relevant key . If only one tubehead is connected then
customization of tubehead 2 is inhibited.
Select the tooth, and then change the set time via the s+ and s- keys.
Customization anyway maintains the one step separation between small-medium-large patients. The "medium"
size is forced during this operation, the relevant lamp lights on, and the time is always displayed (the time vs.
mains voltage compensation is disabled).
