Releasing a cephalometric exposure
NOTE
i
The movements of the unit must not be obstructed by
physical constitution nor clothing, dressings, wheel-
chairs or hospital beds! Perform a test cycle with the
“T”
key, see also “General safety information” .
• Observe the radiation protection regulations
(see also chapter 1 “Identification of warning and
safety information”).
NOTE
i
There must not be any help message displayed in the
comment line of the touchscreen.
The message “
Ready for exposure ” must appear.
ATTENTION
The patient’s arms must hang down freely at the sides,
he/she must not pull up his/her shoulders.
Advise the patient not to move his/her head in any way
during the scan and watch yourself to make sure that this
does not happen!
Trigger the exposure scan by pressing and holding
down the exposure release button (10).
While radiation is active the optical radiation indicator
(32) is illuminated.
In addition, an acoustic signal sounds throughout the
entire radiation time.
ATTENTION
Take care not to let go of the exposure release button
prematurely. Wait until the unit has completed the expo-
sure cycle.
• The exposure cycle is complete when...
... the touchscreen comment line switches from
“ Ex-
posure is performed ” to “ Please wait ”.
... a row of dots “........” appears alternately with the
program number on the remote control display.
...a short pulsed tone sequence also can be heard at
the end of the exposure (this function can be deacti-
vated by your service engineer).
NOTE
i
The end of the exposure cycle can also be seen on the
SIDEXIS monitor, namely when the
progress indicator
shows 100 % and the preview image starts to build up.
Left-handed arm: Scanning operation from front to rear,
secondary diaphragm and sensor remain at the rear in
