D3439.201.07.11.0201.2018 11
4.1.4 Accessories
In order to ensure product safety, this device may be operated only with
original Dentsply Sirona accessories or third-party accessories
expressly approved by Dentsply Sirona. In particular, only the power
cable also supplied or the corresponding original spare part may be
used with the unit. The user is responsible for any damage resulting
from the use of non-approved accessories.
4.2 Opening the processing chamber door during
the machining process
CAUTION
Instruments that continue to run
When the processing chamber door is opened during the machining
process, the instruments could continue to run for a short time.
➢ Be careful not to touch the instruments with your hand or any
other object during this time.
➢ Avoid opening the processing chamber door while the milling and
grinding unit is in operation.
➢ Before you open the processing chamber door, end any actions
that are running by pressing the
"Stop" button on the milling and
grinding unit or in the application software.
4.3 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.

D3439.201.07.11.0201.2018
4.4 Disturbance of data transmission
Note on wireless communication Data communication between the acquisition unit and the CEREC MC/
MC X 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.
Dentsply 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/MC X milling and grinding unit.

5.4.5 Inserting the processing chamber screen and upper
screen
NOTE
Risk of blockage in the cooling circuit
If chips enter into the cooling circuit of the machine, there is a risk that
the cooling circuit will become blocked.
➢ The processing chamber screen is suitable for all restoration and
material types. It is absolutely essential that no chips enter into
the cooling circuit.
Inserting the upper screen
The upper screen enables simpler cleaning of processing chambers
when milling CEREC Guide 2 drilling templates. It can also be used with
other materials, but is particularly helpful when it comes to removing
material waste, which gathers during each milling process of CEREC
Guide 2 on the floor of the processing chamber.
1. Position the upper screen on the existing processing chamber
screen on the floor of the chamber. If needed, you can easily
remove and clean the upper screen. It is essential that the upper
screen is emptied and washed following each milled drilling
template.
2. Check the water level in the water tank following each milled drilling
template, as water is absorbed in the material waste.
5.4.6 Connecting the bar code reader
The bar code reader is optional for the CEREC MC/MC X unit.
Connecting the bar code reader
➢ Plug the bar code reader into the serial interface to the rear of the
milling and grinding unit and secure with screws.
