Perform a movement test running the Dummy panoramic procedure, making sure the movement on the
3 axes X, Y, R (rotation and translation simultaneously) is smooth and without noise. See figure 1, next
page.
To perform a dummy cycle, namely the simulation of an examination without the emission of
X-rays, select any type of panoramic X-ray examination and reset the unit. Once the reset
position has been reached, press the “Reset” button and keep it pressed during the entire
procedure, otherwise the movement will stop.
