Keys and indicator lights
Preprogrammed setting keys and indicator lights
The unit is preprogrammed with exposure parameters -
time and kV values - which can be selected by pressing
these keys. There are nine sets of parameters for both
the child mode and the adult mode: one for each expo-
sure region and one default exposure values, which are
in use when an exposure region is not selected.
The selections that can be made are: molars, premolars
& canines, incisors and occlusal exposure.
Press the desired key once to select the projection of
the maxilla, and press the key twice to select the pro-
jection of the mandible. The indicator light of the se-
lected projection will come on.
Pressing the key a third time will recall the default ex-
posure values.
The preprogrammed settings can be changed by the

SURE VALUES” on page19.
