RF Emissions CISPR 11
Group 1
The ATMOS C 21 / C 31 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.

• 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.
The device may not be used directly next to other devices or piled up with other devices. If operation next to or piled with other
devices is necessary, please watch the device to check its intended operation in this arrangement.
