Information to the User

Note: This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:

--Reorient or relocate the receiving antenna.

--Increase the separation between the equipment and receiver.

--Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.

--Consult the dealer or an experienced radio/TV technician for help.

This device complies with Industry Canada ICES-003: CAN ICES-3 (B)/NMB-3(B).

4. System Description

This chapter describes the context of the CEREC Radio Device by describing the main
function and identifying the system components.

4.1 CEREC System

Mobile acquisition unit and a stationary milling unit.
The acquisition unit generates the restoration data which is to be transmitted to the
milling unit.
The acquisition unit completes this by setting up a TCP/IP connection to the milling unit.
An Ethernet infrastructure is required to facilitate this.
This can be implemented by a standard wired LAN infrastructure, Wi-Fi or the CEREC
Radio Device system as described in this document.

4.2 System Components

The identifiable components and their role in the CEREC system are listed below:

4.3 Main Function

The objective of the CEREC Radio Device is to obtain a reliable wireless data connection
between a stationary milling unit and a mobile acquisition unit. The wireless network
that is created can then be used to transmit time constraint data.

For the acquisition units and milling units there is no difference between the CEREC
Radio Device and a wired LAN; the connection is completely transparent.

4.4 Network Unit

The CEREC Radio Device comprises a number of wireless network units that together
create a wireless network. These network units implement a proprietary Sirona protocol
specially developed to comply with time constraint transmission requirements that
followed from the CEREC Radio Device use cases.

The basic functionality of a network unit is to convert incoming Ethernet data into a
number of wireless packages and forward these to one or more selected neighboring
network units and vice versa. This functionality is comparable to an Ethernet network
switch. As such, this network can be used as a wireless LAN and is completely
transparent for any Ethernet communication.

Using this functionality, a link between two network units can support the data
communication of an acquisition unit and milling unit.

A network unit can appear in four roles:

● Directly connected to a milling unit using a LAN cable and powered by the supplied

wall adapter.

● Built into an acquisition unit where it is directly connected to the internal PC via a

LAN cable and powered via the USB 3.0 connection of the PC.

● Connected to another network unit via a LAN cable and powered by the wall adapter.

● Connected to a LAN infrastructure, i.e. to a hub or switch and powered by the wall

adapter.

The schematic representation of a network unit is shown below.
