Electromagnetic environment
The medical device uses HF energy exclusively for its internal function.
This means that its HF emissions are very low, and it is unlikely that adjacent
electronic devices will receive any interference.
The medical device is intended for use in all facilities, including residential
buildings and facilities that are directly connected (without a transformer) to the
same low voltage network as residential buildings.

Electromagnetic environment
Floors made of timber, concrete or ceramics tiles
are preferred. Where synthetic floor covering is
used, the relative humidity should be at least 30%.
The quality of the mains power supply should
match that of a typical business or hospital
environment.
The quality of the mains power supply should
match that of a typical business or hospital
environment.
In proximity of this medical device, do not operate
devices with unusually strong network-frequency
magnetic fields (transformer stations etc.).
The supply voltage quality should be that of a
typical business or hospital environment. If the user
requires continued function during any interruption
of the energy supply system, we recommend that
the medical device be powered by an uninterrupted
power supply or a battery.
