Warning - Cleaning the unit

ORTHOPANTOMOGAPH OP 2D
Electrostatic Discharge (ESD) can damage or destroy
electronic components.
When servicing the unit take precautions to avoid elec-
trostatic charge build up and discharge (ESD). Follow
the recommendations for the prevention of ESD that
are used in the country in which you are working. If no
recommendations are available, follow the guidelines
below:
- Leave all new or replacement circuit boards and
electrical parts in their protective packaging until the
boards are needed.
- Before handling circuit boards and electrical parts
make sure that any static electricity charge that has
built up in your body is discharged.
- When examining and checking circuit boards use an
antistatic wrist wrap which is connected to a ground
point through a 1 Mohm current limiting cable. For a
ground point use water pipes, radiators or other ob-
jects that are known to be connected to the ground.
Also use a cable to connect the unit to the same
ground potential as the wrist wrap.
- When handling circuit boards hold them by their
edges and do not touch any components or connec-
tors.
- If an antistatic mat is used, connect the wrist wrap
to the mat and the mat to the ground potential.
- Wash the wrist wrap and check that it is in good
condition frequently.
Certain disinfectants and cleaning agents may vaporize
to form an explosive vapour. If such chemicals are used
the vapour should be allowed to disperse before switch-
ing the unit on.
Switch the unit off and disconnect it from the main
power supply before cleaning or disinfecting the unit.
