11.0 Notes on EMC
■ Medical electrical equipment is subject to special precautions with regard to EMC and must be installed acc.
to following EMC notes.
■ Portable and mobile HF communication facilities can influence medical electrical equipment.
■ The use of other accessories, other converters and cables than stated may lead to an increased emission
or a reduced interference immunity of the equipment or system.

Electromagnetic Environment - Guidance
The ATMOS Variotherm plus uses RF energy only
for its internal function. Therefore, its RF emissions
are very low and are not likely to cause any interfe-
rence in nearby electronic equipment.
The ATMOS Variotherm plus is suitable for use in
all establishments, including domestic, and those
directly connected to the public low-voltage power
supply network that supplies buildings used for
domestic purposes.
