Electromagnetic environment –
guidelines
The flooring should be wood or concrete or be covered
with ceramic tile. If the floor material is a non-conduc-
tive, synthetic material, the relative humidity of the air
must be at least 30%
The quality of the mains supply voltage should be
the same as that of a typical commercial or hospital
environment.
The quality of the mains supply voltage should be
the same as that of a typical commercial or hospital
environment.
The quality of the mains supply voltage should be
the same as that of a typical commercial or hospital
environment.
If the user requires continued operation during power
interruptions, it is recommended that the device be
powered from an uninterruptable power supply or a
battery.
Should interference occur, it may be necessary to place
the KaWe MedCenter 5000 further from the source line
frequency magnetic fields or to fit it with a magnetic
shield: the line frequency magnetic field should be
measured at the intended use site to ensure that it is
not large enough to cause a disturbance.
