Operating Instructions CEREC MC XL Premium Package 4.4 Disturbance of data transmission
båÖäáëÜ
4.4 Disturbance of data transmission
Brazilian market
The Hoeft & Wessel (H&W) wireless interface is not available for the
Brazilian market.
The information on this interface contained within this document is only
applicable in countries outside of Brazil, where these wireless modules
are approved.
Note on wireless communication
Note on wireless communication Data communication between the acquisition unit and the CEREC MC XL
Premium Package milling unit should preferably be established via the
wireless H&W interface 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 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 rear of the
CEREC AC is occupied by another plug, remove this H&W wireless
interface connection and instead connect the LAN cable with the CEREC
MC XL Premium Package milling unit.
