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 Varioair 3 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.
The ATMOS Varioair 3 is suitable for use in all es-
tablishments, including domestic, and those directly
connected to the public low-voltage power supply
network that supplies buildings used for domestic
purposes.
