Guidelines and MANUFACTURER-Declaration - ELECTROMAGNETIC INTERFERENCE IMMUNITY
The KaWe MedCenter® 5000 is designed to be used in the types of ELECTROMAGNETIC ENVIRONMENTS listed below.
The customer or user N13) is responsible for ensuring that this device is used in such an environment.

The flooring should be wood or concrete or be covered
± 6kV contact
with ceramic tile. If the floor material is a non-conduc-

If the user requires continued OPERATION during power
interruptions, it is recommended that the device be

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 magne-
3 A/m
tic 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.
