protective measures first.
➢ Do not establish any connections between these connectors
without applying ESD protective measures first.

4.3 Electrostatic charge
Sirona Dental Systems GmbH
Operating Instructions CEREC AC
16
4.3.2 ESD protective measures
ESD ESD stands for ElectroStatic Discharge.
ESD protective measures ESD protective measures include:
● Procedures for preventing electrostatic charge build-up (e.g. air
conditioning, air moistening, conductive floor coverings and non-
synthetic clothing)
● Discharging the electrostatic charges of your own body on the frame
of the UNIT, the protective ground wire or large metallic objects
● Connecting yourself to ground using a wrist band.
Training We therefore recommend that all persons working with this system be
instructed on the significance of this warning label. Furthermore, they
also should receive training in the physics of electrostatic discharges
which can occur in the practice and the destruction of electronic
components which may result if such components are touched by
electrostatically charged USERS.
The content of this training is explained in the Chapter "About the
physics of electrostatic charges" [→16].
4.3.3 About the physics of electrostatic charges
What is an electrostatic charge? An electrostatic charge is a voltage field on and in an object (e.g. a
human body) which is protected against conductance to ground
potential by a nonconductive layer (e.g. a shoe sole).
Formation of an electrostatic charge Electrostatic charges generally build up whenever two bodies are
rubbed against each other, e.g. when walking (shoe soles against the
floor) or driving a vehicle (tires against the street pavement).
Amount of charge The amount of charge depends on several factors:
Thus the charge is higher in an environment with low air humidity than
in one with high air humidity; it is also higher with synthetic materials
than with natural materials (clothing, floor coverings).
Electrostatic discharge must be preceded by electrostatic charging.
The following rule of thumb can be applied to assess the transient
voltages resulting from an electrostatic discharge.
An electrostatic discharge is:
● perceptible at 3,000 V or higher
● audible at 5,000 V or higher (cracking, crackling)
● visible at 10,000 V or higher (arc-over)
The transient currents resulting from these discharges have a
magnitude of 10 amperes. They are not hazardous for humans because
they last for only several nanoseconds.

4.4 Wireless phone interference with equipment
63 33 582 D3492
D3492.201.01.22.0210.2018 17
Background Integrated circuits (logical circuits and microprocessors) are used to
implement a wide variety of functions in dental/X-ray/CAD/CAM
systems.
The circuits must be miniaturized to a very high degree in order to
include as many functions as possible on these chips. This leads to
structure thicknesses as low as a few ten thousandths of a millimeter.
It is obvious that integrated circuits which are connected to plugs
leading outside of the unit via cables are sensitive to electrostatic
discharge.
Even voltages which are imperceptible to the user can cause
breakdown of the structures, thus leading to a discharge current which
melts the chip in the affected areas. Damage to individual integrated
circuits may cause malfunction or failure of the system.
To prevent this from happening, the ESD warning label next to the plug
warns of this hazard. ESD stands for ElectroStatic Discharge.
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.
4.4 Wireless phone interference with equipment
The use of mobile wireless phones in practice or hospital environments
must be prohibited to ensure safe operation of the unit.
4.5 Disturbance of data transmission
Note on wireless communication Data communication between the acquisition unit and the CEREC MC
XL milling and grinding unit should preferably be established via the
wireless interface CEREC Radio Device or WLAN.
As for all wireless connections (e.g. cell phones), heavy utilization of the
available radio channels or shielding caused by building installations
(e.g. metal-shielded X-ray enclosures) may impair the quality of the
connection. This may become noticeable through a reduction in range
and/or a slower data transmission rate. In extreme cases, it will be
impossible to establish a wireless connection at all.
Sirona has selected the best possible configuration for data
communication via the wireless interface (CEREC Radio Device) or
WLAN, which generally ensures perfect functioning of this connection.
However, in individual cases unrestricted wireless data communication
may be impossible for the reasons mentioned above and/or due to local
circumstances. In such cases, a cable LAN connection should be
selected to ensure uninterrupted operation. If the only LAN interface on
the rear of the CEREC AC is occupied by another plug, remove this
wireless interface connection, and instead connect the LAN cable with
the CEREC MC XL milling and grinding unit.
