The top holes are exclusively reserved for the installation of Stereotix 2 or
Senovision Stereotactic positioner, or for making exposures of specimens or
core biopsy samples.
When making exposures of specimens or core biopsy samples, the magnification
plate can be snapped onto the top holes with the Positioning Arm remaining at 0
degree. The magnification factor are then 1.6 for 560 SID, 1.7 for 610 and 1.9 for
660.

Compression is controlled by two pairs of compression/decompression footswitches
6 placed on the floor.
Compression force, speed of compression and decompression height are
programmed by the SET-UP functions of the system.
Manual adjustment is via thumbwheels located one on either side of the compression
paddle arm.
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 occurred during an
examination, a force of around 5 daN could remain on the compression paddle. To
disengage the patient, the paddle should be gently raised to counteract this
compression force.
Pressing the compression pedals and moving the thumbwheels illuminates the
centering light.
Optional 4–switch pedal: Optional 4–switch pedal is available with both column
Up/Down and Paddle Compression controls. See below for symbol meaning:

Compression paddle change: Slide the paddle arm sideways from the compression
paddle support.
For best results in AOP, it is recommended to match the format of the compression
paddle with the format of the bucky when in contact mode, i.e. use the 18 x 24
compression paddle with the 18 x 24 bucky and use the 24 x 30 compression
paddle with the 24 x 30 bucky.
