Notes on EMC
12.0 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.
Guidelines and Manufacturer´s Declaration - Emissions
The ATMOS
®
E 341 Battery is intended for use in the electromagnetic environment specified below. The
customer or user of the ATMOS
®
E 341 Battery should ensure that it is used in such an environment.

RF Emissions acc.to CISPR 11
Group 1
The ATMOS
®
E 341 Battery uses RF energy
only for its internal function. Therefore, its HF
emissions are very low and it is unlikely that
nearby electronic devices will be affected.

E 341 Battery 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.
