Note: As a safety measure, the compression system is fitted with magnetic braking to avoid the
paddle falling in the event of a power cut. If such a power cut occurs during an examination, a

raise the paddle steadily (do not try to lift it quickly) to counteract this compression force.
Note: Pressing a compression pedal or moving one of the thumbwheels illuminates the centering
light.
