6 Using the unit
4. Press and hold down the exposure button. During the exposure you hear an audible
signal and the exposure warning symbol on the touch screen display appears.
NOTICE! When taking FOV 130x150 mm (optional) image, the unit will
take two sub-scans with automatic upward movement relative to the
patient. Upward movement is made in between the two sub-scans. One
single exposure button press is needed to obtain FOV 130 x 150 image. It is
recommended to inform patient about the movement prior to examination

stop the movement. If the exposure button is released between the sub-scans
the sequence can be resumed manually by pressing the carriage up button on
control panel.
