1 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 anes-
thetics. 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 elec-
tronic parts (cables/sensors/PCBs) before turning on the unit.
The chin support can be cleaned with NON-ALCOHOLIC disinfection solutions.
All the removable patient support parts can be autoclaved up to 135°C or cleaned with alco-
hol-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 Operating checks

To guarantee user and patient safety and to ensure consistent image quality, the X-ray unit
must be checked and recalibrated by a qualified Planmeca service technician once a year or
after every 10 000 exposures if this is sooner.
The following operating checks have to be performed on a regular basis:
Exposure indicators
Confirm that the exposure indicator lights turn on in the control panel (GUI and/or NUI) and in
the exposure switch for the length of the exposure. Additionally, check also the (optional)
external exposure indicator, if the unit is equipped with such.
Exposure warning signal
Confirm that the units buzzer comes on for the length 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. Check that this buzzer also
comes on for the length of the exposure if it is enabled.
