CEPHALOSTAT ADJUSTMENT

NOTE

Switch the unit off after all the checks and adjustments have been performed, before tak-
ing any patient exposures.

6.1

Preparations before adjustments

Press the ceph mode selection key to enter the ceph mode if you are not already in it. The rotat-
ing unit will move automatically to the correct position for taking cephalometric exposures. The
latest used image area will be automatically selected.

Remove the inner cover from tube head assembly. Four screws hold the tube head cover in posi-
tion, these are located at the rear of the tube head assembly.
