Guidance and manufacturer’s declaration – electromagnetic
emissions and immunity
Medical Electrical Equipment needs special precautions regarding EMC and needs to be
installed and put into service according to EMC information provided in this document.
Guidance and manufacturer’s declaration – electromagnetic emissions
The device is intended for use in the electromagnetic environment specified below. The customer or the user of the
device should assure that it is used in such an environment.
Emissions test Compliance Electromagnetic environment - guidance
RF emissions CISPR11 Group 1 The device 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.
RF emissions CISPR 11 Class B The device is suitable for use in all establishments,
including domestic establishments and those directly
connected to the public low-voltage network that
supplies buildings used for domestic purposes.

Warnings: The device should not be used adjacent to or stacked with other equipment.
If adjacent or stacked use is necessary, the device should be observed to verify normal operation in the
configuration in which it will be used.
The use of accessories (eg, humidifiers) other than those specified in this manual is not recommended. They may
result in increased emissions or decreased immunity of the device.
