6.8 Positioning the X-ray head
Position the X-ray head so that the cone is aligned with the image receiver.
BALL JOINT TECHNOLOGY
NOTE: This section applies only to models RX DC REF: MRPU*****
(Character * can be any alphanumeric value)
In the versions equipped with ball joint, the X-ray head can freely rotate on both its
horizontal and vertical axis.
An electromechanical brake initially locks the X-ray head. To release the head and let
it rotate on the positioning ball, work on the touch sensitive unlocking areas located on
it (see points A in the gure on the side).
Touching the unlocking areas allows positioning the X-ray head at the desired angle to
perform the exposure. To lock it again, simply release the unlocking areas.
NOTE: Firmly hold the X-ray head with both hands when putting it in
place.
It is possible to set a safety unlocking mode that allows the head to be turned only by
pressing both unlocking keys. This prevents the head from unlocking unexpectedly
after one of the two unlocking keys has been accidentally pressed. To activate this
mode, see section “Setting the safety unlock mode”.
