SYSTEM MAINTENANCE

1.1

Cleaning

CAUTION When disinfecting the unit surfaces, the unit should be turned off. The
unit must not be exposed to gaseous disinfectants or explosive
anaesthetics. Never spill any liquids into the unit. If that happens,
make sure that the liquid did not come into contact with any of the
internal electronic parts (cables/sensors/PCBs) before turning the X-
ray unit on.
All removable patient support parts can be autoclaved up to 135°C or cleaned with
alcohol-based solutions.
The patient support handles can be cleaned with alcohol-based solutions.
Other unit surfaces, including the control panel display, can be cleaned with a soft cloth
damped in a mild cleaning solution.
NOTE Do not use cleaning agents in aerosol or spray form directly on unit surfaces.

Operator's checks

1.2.1 Exposure indicators
Confirm that the exposure indicator lights on the control panel display (GUI) and on the
exposure switch turn on for the whole duration of the exposure. Additionally, check the
operation of the (optional) external exposure indicator, if the unit is equipped with one.
1.2.2 Exposure warning signal
Confirm that the unit's buzzer comes on for the whole duration of the exposure. The
exposure switch also contains a buzzer. However, this buzzer can be disabled or enabled
(from within the exposure switch assembly) depending on local regulations. If the
exposure switch buzzer is enabled, check that it comes on for the whole duration of the
exposure.
1.2.3 Exposure switch
Confirm that the exposure switch requires continuous activation to maintain the exposure.
Releasing the exposure switch button during radiation should stop the exposure and
produce an error message. Make a visual check and check for possible wear or damage
of the exposure switch spiral cable. Replace it if necessary.
1.2.4 Labels
Check that no labels are detached or worn and that they are all legible.
