Electromagnetic Compatibility; Reducing Electromagnetic Interference - Philips SureSigns VS1 Manuel D'utilisation

This document describes the status of the VS1 monitor related to the internationally accepted standard for
electromagnetic compatibility, IEC 60601-1-2, which in the European Union has been adopted as the
European Norm, EN 60601-1-2.
Medical electrical equipment can either generate or receive electromagnetic interference. This product has
been evaluated for electromagnetic compatibility (EMC) with the appropriate accessories according to IEC
60601-1-2:2001, the international standard for EMC for medical electrical equipment. This IEC standard
has been adopted in the European Union as the European Norm, EN 60601-1-2:2001.
Radio frequency (RF) interference from nearby transmitting devices can degrade performance of the
monitor. Electromagnetic compatibility with surrounding devices should be assessed prior to using the VS1
monitor.
Fixed, portable, and mobile radio frequency communications equipment can also affect the performance of
medical equipment. See your service provider for assistance with the minimum recommended separation
distance between RF communications equipment and the VS1 monitor.
The cables, sensors/transducers, and other accessories for which compliances is claimed are listed in the
Service and User documentation accompanying the monitor.
Warning The use of accessories, transducers and cables other than those specified in the VS1 documentation
can result in increased emissions or decreased immunity of the monitor.
The VS1 monitor should not be used next to or stacked with other equipment. If you must stack the
product, you must check that normal operation is possible in the necessary configuration before the
VS1 is used.

Reducing Electromagnetic Interference

The VS1 monitor and associated accessories can be susceptible to interference from other RF energy
sources and continuous, repetitive, power line bursts. Examples of other sources of RF interference are
other medical electrical devices, cellular products, information technology equipment, and radio/television
transmission. If interference is encountered, as demonstrated by artifact on the ECG or dramatic variations
in physiological parameter measurement values, attempt to locate the source. Assess the following:
• Is the interference due to misplaced or poorly applied electrodes or sensors? If so, re-apply electrodes
and sensors correctly according to directions in this manual.
• Is the interference intermittent or constant?
• Does the interference occur only in certain locations?
• Does the interference occur only when in close proximity to certain medical electrical equipment?
• Do parameter measurement values change dramatically when the AC line cord is unplugged?
Once the source is located, attempt to attenuate the interference by distancing the monitor from the source
as much as possible. If assistance is needed, contact your local service representative.
