Notes On Emc - Atmos Varioair 3 Operating Instructions Manual

11.0 Notes on EMC

• Medical electrical equipment is subject to special precautions with regard to EMC and must be installed according to the follow-
ing EMC notes.
• Portable and mobile RF communication facilities can influence medical electrical equipment.
• The use of other accessories, converters, and cables than stated may lead to an increased emission or a reduced interference
immunity of the equipment or system.

Electromagnetic Environment
Group 1 The Varioair 3 uses HF energy for its internal functions. There-
fore, its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.
Class B
Class A The Varioair 3 is suitable for use in all establishments, including
domestic and those connected directly to a public power supply
network that supplies buildings used for residential purposes.
