6.5 Information about electromagnetic compatibility

Electrical medical equipment is subject to special precautionary measures with regard
to electromagnetic compatibility (EMC). Such equipment must only be installed and
operated in accordance with EMC instructions.
Portable and mobile high­frequency communication devices can disrupt electrical
medical equipment. Using accessories, converters and power cords other than those
specified, with the exception of converters and power cords that the manufacturer of
the medical electrical device sells as spare parts for internal components, can result in
higher emission levels or lower the resistance to interference of the device.
The device must not be placed directly beside or on top of other devices for operation.
If the medical electrical device must be placed beside or on top of other devices to op­
erate it, it should be monitored constantly to ensure that it is operating properly in the
arrangement used.
Technical data on electromagnetic compatibility (EMC instructions) in table format are
included with the device. It can also be ordered from PARI GmbH or downloaded from
the internet at www.pari.de/en/products under "Technical Data" on the respective
product page.

6.6 Recommended safety distances

Recommended safety distances between portable and mobile high­frequency (HF)
telecommunication devices and the device:
The product is intended for operation in an electromagnetic environment in which radi­
ated HF transients are monitored. The user can help to prevent electromagnetic inter­
ference by observing the minimum safety distances between portable and mobile HF
communication equipment (transmitters) and the product, as recommended below in
accordance with the maximum output power of the communication device.
Safety distance depending on transmitting frequency:
Rated power of the
transmitter
0.01 W
0.1 W
1 W
10 W
100 W
For transmitters whose rated power does not appear in the table above, the safety
distance can be calculated using the equation associated with the respective column,
where "P" is the rated power of the transmitter in Watt (W) according to the informa­
tion supplied by the device manufacturer.
