CAUTION
Risk of injury or damage to components from electrostatic discharge
For electrical components labeled with an ESD warning label, observe

➢ Apply the ESD protective measures.
➢ Do not touch connector pins or sockets without applying ESD
protective measures first.
➢ Do not establish any connections between these connectors without
applying ESD protective measures first.
Lower warning label
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 nonsynthetic 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" [ → 17].

Operating Instructions for the acquisition unit CEREC AC 4.3Electrostatic charge
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:
bеЦдблЬ
● 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.
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.
62 31 174 D3492
D3492.201.01.17.02 12.2015
Connector pins or sockets bearing ESD warning labels must not be
touched or interconnected without ESD protective measures.

Note on wireless communication Data communication between the acquisition unit and the CEREC MC XL
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.
Disturbance of data transmission
Note on wireless communication
grinding unit should preferably be established via the wireless interface
(H&W or 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 (H&W and 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 grinding unit.

Remark 1
The higher frequency range applies at 80 MHz and 800 MHz.
Remark 2
These guidelines may not be applicable in all cases. The propagation of

buildings, objects and persons.
1. Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio,
AM/FM radio and TV broadcasts, cannot be predicted theoretically
with accuracy. An investigation of the location is recommended to
determine the electromagnetic environment resulting from stationary
RF transmitters. If the measured field strength in the location in which
the UNIT is used exceeds the applicable RF compliance level
specified above, the UNIT should be observed to verify normal
operation. If unusual performance characteristics are observed, it
may be necessary to take additional measures such as reorientation
or repositioning of the UNIT.
2. Over the frequency range 150kHz to 80 MHz, field strengths should
be less than 3 V/m.

The UNIT is intended for operation in an electromagnetic environment,
where radiated RF interference is checked. The customer or the user of
the UNIT can help prevent electromagnetic interference by duly
observing the minimum distances between portable and/or mobile RF
communication devices (transmitters) and the UNIT. These values may
vary according to the output power of the relevant communication device
as specified below.
For transmitters whose maximum nominal output is not specified in the
above table, the recommended working clearance d in meters (m) can be
determined using the equation in the corresponding column, where P is
the maximum nominal output of the transmitter in watts (W) specified by
the transmitter manufacturer.
Remark 1
An additional factor of 10/3 is applied when calculating the recommended
working clearance between transmitters in the 80 MHz to 2.3 GHz
frequency range in order to reduce the probability that a mobile/portable
communication device unintentionally brought into the patient area could
lead to interference.
Remark 2
These guidelines may not be applicable in all cases. The propagation of
electromagnetic waves is influenced by their absorption and reflection by
buildings, objects and persons.

Battery-backed operation (optional)
Introduction
The acquisition unit PC has a battery-backed power supply. It is thus
possible to operate the acquisition unit for a short time with no line voltage
connected.
CAUTION
No treatment without connected line voltage
Patients must not be treated (generation of intra-oral impressions)
unless the unit is connected to the practice's electricity-supply system.
The following parameters are constantly checked by the installed
monitoring software in order to monitor the battery back-up function:
● Line voltage present
● Charge set of storage battery pack
● Fan function
● Temperature of power supply
When the unit is running in the battery-powered mode, this is indicated by
a message displayed at the bottom of the screen. It is accompanied by a
rhythmic beep.
This beep changes to a continuous signal 30 seconds before the system
shuts down due to insufficient battery power. A corresponding display
then appears in the center of the screen. The user thus has time to finish
his last actions on the PC.

The temperature monitor has two message thresholds.
The first message threshold is output as the message
"High" in the temperature result field. The "High" reading
is displayed in the red-and-black flashing mode. No
countdown window appears since, depending on the
load and ambient conditions, the unit can keep operating
for a few minutes, or even for a longer period of time if the
temperature level decreases again. Direct shutdown
occurs if the 2nd threshold is reached.
No battery is inserted.

If the Bluecam is held at an oblique
angle to the prepared insertion
axis, the wall closer to the lens will
be registered with an undercut; the
wall further away from the lens will
be fully displayed, thus causing
the occlusal margin angle to be

Operating Instructions for the acquisition unit CEREC AC 7.3Preparations
Depth of focus and focusing
The telecentric optics, which cause objects to be displayed with a
constant size regardless of how far away from the prism they are, have a
depth of focus which is sufficient to capture deep preparations.
The image definition is determined by the distance between the Bluecam
and the preparation.
➢ Check the monitor to determine whether the cervical steps and the
occlusal margins are simultaneously displayed with sufficient
definition. The center of focus should be aimed at the vertical center
of the preparation, e.g. at the occlusal base.
Angle of incidence/steepness
If the angle of incidence of the Bluecam is too large, the mesial cervical
step moves outside of the focal depth range of the Bluecam as shown in
the illustration. Distally, the cervical step is concealed by the distal
neighbors with the excessively steep angle shown here. This leads to an
inadequate "optical impression".
bеЦдблЬ
7.3
Preparations
7.3.1 Surface
The surface of the preparation is captured with an especially fast and
precisely functioning optical measuring technique. This measuring
technique requires a non-glare, diffusely reflecting surface. The surface
must be covered with a thin, opaque coating in order to obtain even light
dispersion, exclude blinding effects and obtain clear surface definition.
This is the precondition for a high-contrast image and good optical
acquisition.
NOTICE
Thin and even coating
Please try to deposit as thin and even a coating as possible on all
surfaces, especially in the edge and marginal regions.
NOTE on extraoral 3D imag e acquisition
NOTICE
The extraoral 3D image acquisition of a model may be adversely
affected by bright light.
Set the model up so that it is not located directly in the beam path of an
extreme light source and not exposed to direct sunlight.

7.3Preparations Operating Instructions for the acquisition unit CEREC AC
7.3.2 CEREC Optispray
1. Clean and dry the surface to be coated.
2. Place the spray head with cannula/nozzle onto the spray can.
3. Check that the cannula/nozzle is seated correctly before each use by
pulling it gently.
4. Shake the container before use.
5. Cover the respective area with the spray in a targeted manner. The
cannula/nozzle can be rotated as required to enable optimal coating
from all directions. The spray nozzle should be held approx. 10-15
mm away from the object.
6. Take an optical impression with the Bluecam as usual.
7. After taking the 3D optical impression, clean the surface with an air/
water spray.
8. Replace the cannula/nozzle after each use.
7.3.3 Direction of application
right wrong
It is essential that the material is applied perfectly, especially in the edge
and marginal areas. It is therefore advisable to aim the cannula directly at
all edge and marginal areas. Spraying directly onto the base may result
in an excessively thick layer, which in turn can result in fitting inaccuracy.
7.3.4 Marking the cervical step
The cervical and lateral edges are coated from the proximal direction.
If the cervical step is located at the same height as the edge of the
gingiva, the spray may cover the borderline between these two
structures.
This boundary can be marked again by running a fine probe along the
step or laterally pulling a rubber cofferdam.
Before you start spraying, you can loosely insert dental floss and then
carefully remove it again.
NOTICE
Avoid applying too much or not enough coating. We recommend
blowing the object clean with compressed air after spraying.

After around 1000 buffer cycles the capacity of the battery fades due to
the nature of the battery technology used.
If the buffer times are too short, you should replace the battery.
The battery is permanently charged during operation on mains voltage.
This allows brief buffer operation after one hour of charging.
For a complete charge, the battery must be charged without interruption
for at least 12 hours. Keeping the acquisition unit connected to the mains
voltage and the power switch on is sufficient here. The PC does not have
to be switched on for the charging process.
