Group 1
The ATMOS
®
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.
