PREVENTIVE MAINTENANCE
1 SYSTEM MAINTENANCE
1.1 Cleaning
CAUTION When disinfecting the unit surfaces, always disconnect the unit from the mains. The
unit must not be exposed to gaseous disinfectants or explosive anesthetics. Never
spill any liquids into the unit.
The chin support and the Ceph cassette holder can be cleaned with NON-ALCOHOLIC disin-
fection solutions.
The bite piece of the chin rest can be removed and autoclaved. It can also be cleaned with
alcohol-based solutions. The patient support handles can be cleaned with alcohol-based
solutions.
Other unit surfaces can be cleaned with a soft cloth damped in a mild cleaning solution.
1.2 Operator’s checks
Exposure indicators
Confirm that the exposure indicator lights turn on in the control panel and in the remote con-
trol for the length of the exposure.
Exposure warning signal
Confirm that the buzzer comes on for the length of the exposure. If needed, adjust the tone of
the signal, see section “EXPOSURE WARNING SIGNAL ADJUSTMENT” on page D-26.
Exposure switch
Confirm that the exposure switch requires continuous activation to maintain the exposure.
Releasing the exposure switch during the radiation should produce the ER00 message on the
displays (clear it by pressing the CTL-key once). Make a visual check that the exposure
switch spiral cable is not damaged.
Labels
Check that no labels are detached or worn and that they are all legible.
