Compex Wireless - Manual (Page 146)

145
The Compex Wireless stimulator needs special precautions regarding EMC and needs to be installed and put into service according to the EMC
information provided.
Portable and mobile RF communications equipment can affect the Compex Wireless stimulator.
The use of Accessories, transducers, and cables other than those specified by the manufacturer, may result in increased Emissions or decreased
Immunity of the Compex Wireless stimulator.
The Wireless stimulator should not be used adjacent to or stacked with other equipment and if adjacent or stacked use is necessary, the Compex
Wireless stimulator should be observed to verify normal operation in the configuration in which it will be used.
GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC EMISSIONS
The Compex Wireless stimulator is intended for use in the electromagnetic environment specified below. The customer or the user of the
Compex Wireless stimulator should assure that it is used in such an environment.
EMISSION TESTS COMPLIANCE ELECTROMAGNETIC ENVIRONMENT – GUIDANCE
Radiated Emissions CISPR 11 Group 1 The Compex Wireless uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause
any interference in nearby electronic equipment.
Conducted Emissions CISPR 11 Class B The Compex Wireless is suitable for use in all establishments,
including domestic establishments and those directly connected to
the public low-voltage power supply network that supplies buildings
used for domestic purposes.
