This appendix lists the tests and compliance levels that make the SureSigns VS2
monitors suitable for use in the specified electromagnetic environment according to
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 EN/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,
Radio frequency (RF) interference from nearby transmitting devices can degrade performance of the
product. Electromagnetic compatibility with surrounding devices should be assessed prior to using the
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 product.
The cables, sensors/transducers, and other accessories for which compliance is claimed are listed
earlier in the Instructions for Use.
• Use of accessories, transducers, and cables other than those specified may result in increased
emissions and/or decreased immunity of the SureSigns VS2
• The SureSigns VS2
with other equipment. If adjacent or stacked use is necessary, the monitor should be
observed to verify normal operation in the configuration in which it is used.
Reducing Electromagnetic Interference
The SureSigns VS2
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 dramatic variations in physiological parameter measurement values, attempt to locate the
source. Assess the following:
Is the interference due to misplaced or poorly applied sensors? If so, re-apply sensors correctly
according to directions in the product's Instructions for Use.
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
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 product from the
source as much as possible. If assistance is needed, contact your local service representative.
