3-4-3 EMI Protection
This unit has been designed to minimize the effects of Electo-Magnetic Interference (EMI). Many of the
covers, shields, and screws are provided primarily to protect the system from image artifacts caused by
this interference. For this reason, it is imperative that all covers and hardware are installed and secured
before the unit is put into operation.
Ensure that the system is protected from electromagnetic interference (EMI), as follows:
• Operate the system at least 15 feet away from equipment that emits strong electromagnetic
radiation.
• Operate the system in an area enclosed by walls, floors and ceilings comprised of wood, plaster or
concrete, which help prevent EMI.
• Shield the system when operating it in the vicinity of radio broadcast equipment, if necessary.
• Do not operate mobile phones or other EMI emitting devices in the ultrasound room.
• Verify that all EMI rules listed in the following table are followed:
The Voluson® 730Expert
ultrasound unit is approved for use in hospitals, clinics and other
environmentally qualified facilities, in terms of the prevention of radio wave interference. Operation of
the ultrasound unit
in an inappropriate environment can cause electronic interference to radios and
television sets situated near the medical equipment.
For further details and EMI Prevention/Abatement refer to Section 2-2-3 "EMI Limitations" on page 2-4.
