6 Electromagnetic compatibility (EMC)

6.1 General hints

This device complies with the limits set for medical electrical devices of group 1,
class B (as per EN 60601-1-2). The device is suitable for home healthcare and
professional health institutes environments.
The installation and use of this electrical medical device requires
special precautionary measures as outlined in the EMC information
below.
Do not install the appliance near active surgical high-frequency devices
and in radio-frequency-screened rooms of a ME system for magnetic
resonance reproduction where high intensity of electro-magnetic
interferences occurs.
Please avoid to operate the appliance beside or stacked on other
devices, as this may cause incorrect measuring results. If such use
should be required, this appliance and the other devices should be
observed, in order to ensure that they work normally.
Using accessories, transformers and other cables than the specified
ones or delivered by the manufacturer together with the appliance,
could have as consequence reinforced electromagnetic radiation or
reduced electromagnetic immunity to interference and by that way
reduced functionability.
Portable radio-frequency communication equipment (including
periphery as well as antenna cable and external antennae) should be
placed from any part of the MPN (including the cables authorised by
manufacturer) at a distance of at least 30 cm (12 inches). Otherwise
the performance of the appliance could drop down.
Note: The emission characteristics of this appliance allow its use in industrial areas
and in hospitals (CISPR 11 category A). If it is used in residential areas (where CISPR
11 category B normal is required), this appliance cannot ensure sufficient protection
against radio-frequency-communication services. In order to obtain reasonable results,
the user should apply measures for weakening the intensity, e.g. install the device in
another site or re-align it.
Electromagnetic compatibility (EMC) describes a device's ability to perform reliably
within an electromagnetic environment without causing there inadmissible
electromagnetic interference at the same time. Amongst other things, such
disturbances may be transmitted by connecting cables or by the air.
Inadmissible interferences from the environment may result in wrong displays,
inaccurate measured values or incorrect behaviour of the medical device. The
