These buttons are used to adjust the AEC cut-off dose (and patient entrance

Density can be increased and decreased in a range of -4 to +4. Each step is a
change of one exposure step. An exposure step is a change of approximately
-20% or +25% in dose. When disabled, the density range number appears in
black.
