8.2.1 Performing a programmed exposure
If the previous examination was carried out in manual exposure mode,
press one of the size selection or anatomic selection keys to switch to
programmed exposure mode.
In programmed mode it is possible to change the size, type of tooth and
kV value.
Each time the "Size selection" key is pressed , indicated
acoustically, the Large patient / Normal patient / Small patient selection
changes.
To change the selection of the type of tooth, use the "Tooth anatomic
selection" key .
Each time this key is pressed the selection of the type of tooth changes in
rotation. This is signalled acoustically and shown on the display.
Based on the type of film that is selected, the pre-set times are provided
in Table 1.

multiplicative factor. It is possible to request this setting from the
technician during installation.
