4.2 Milling unit
4.2.1 Safety information for the scanner (option)
Safety informa tion for the scan ner
The milling unit complies with Laser class 1. It poses no hazard of any kind.
The laser itself is in Laser class 2 and can pose a hazard to the skin and eyes.
It is located on the left motor mount in the scanner.
WARNING
Laser radiation hazard
Gazing into the beam for extended periods of time can damage a person's
vision.
Never look directly into the laser beam and do not use any optical devices
for this purpose.
The laser beam emerges at right angles to the window of the scanner.
CAUTION
If any operating or adjusting devices other than those specified here are
used or other methods are employed, this can lead to dangerous exposure
to radiation.
NOTICE
Laser beam
Power: < 1 mW
Wavelength: 670 nm
Aperture angle: > 10 mrad
WARNING
Check the scanner for visible signs of damage before each scanning
operation.
Check the door of the milling chamber for visible signs of damage before
each milling operation.
WARNING
Installing and removing the scanner
Only service engineers may install or remove the scanner.

Operating Instructions CEREC MC XL Wireless phone interference with equipment
båÖäáëÜ
4.2.2 Milling chamber door open during the milling
operation
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.
4.4 Disturbance of data transmission
Note on wireless communication
Note on wireless communication The data communication between the acquisition unit and the CEREC MC XL
milling unit should preferably be implemented via the wireless H&W interface
or WLAN. As for all wireless connections (e.g. mobile telephones) 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.
Sirona has selected the best possible configuration for data communication
via the wireless H&W interface or WLAN, which generally provides 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 backside of the CEREC AC is occupied by another plug,
remove this connection of the H&W wireless interface and instead connect
the LAN cable with the CEREC MC XL milling unit.
WARNING
Milling instruments that continue to run
When the milling chamber door is opened during the milling operation, the
milling instruments could continue to run for a short time.
➢ Be careful not to touch the milling instruments with your hand or any
other object during this time.
➢ Avoid opening the milling chamber door while the milling unit is in
operation.
➢ Before you open the milling chamber door, end any actions that are
running by selecting the "Stop" key on the milling unit or in the
application software.

Making the connection
Connect access point
➢ Connect the LAN port A of the milling unit and the access point, using the
network cable (10m, Order No.: 61 51 521).
ªThe access point is pre-configured at the factory for this application.
Positioning the access point 1. As a test, place the access point near the milling unit at head level or
higher.
2. Perform a communication test as described in the separate instructions
(see "Operating MC XL via WLAN in infrastructure mode", chapter "Final
work, analyzing connection quality"). If applicable, follow the instructions
on changing channels.
3. After you have found the optimum setting, take the acquisition unit and
place it in the position in which it will be operated that is farthest away
from the access point.
4. From this position, repeat the communication test you conducted earlier.
If the results are satisfactory, leave the access point permanently in this
position.
5. If the results are not satisfactory, position the access point outside of the
room in which the milling unit is located and repeat the communication
test.
ªIf the connection quality is still not adequate, WLAN communication
cannot be easily achieved under the local conditions. In this case, ask
your network administrator for assistance.
5.4.5.5 Operating several milling units over one access point
To operate several MC XL milling units over one access point, you need the
following additional components:
