Instructions for Use Fabius MRI SW 3.n 201
Technical Data
Electromagnetic immunity
The Fabius MRI is intended for use in the electro-
magnetic environment specified below. The user of
the Fabius MRI should assure that is used in such
an environment.
Immunity against IEC 60601-1-2 test level Compliance
level (of this
equipment)
Electromagnetic environment

ceramic tile. If floors are covered with
synthetic material, the relative humid-
ity shall be at least 30 %.
