4.4

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.

4.5

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 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 milling unit.
