Equipment being returned must be clean and free of blood and other infectious substances.
GEMS policy states that body fluids must be properly removed from any part or equipment prior to
shipment. GEMS employees, as well as customers, are responsible for ensuring that parts/equipment

with human blood that are now caked with dried blood; or which were used or intended for use in patient
care” are “regulated medical waste” for transportation purpose and must be transported as a hazardous
material.
Section 1-4
Electromagnetic Compatibility (EMC)
1-4-1 What is EMC?
Electromagnetic compatibility describes a level of performance of a device within its electromagnetic
environment. This environment consists of the device itself and its surroundings including other
equipment, power sources and persons with which the device must interface. Inadequate compatibility
results when a susceptible device fails to perform as intended due interference from its environment or
when the device produces unacceptable levels of emission to its environment. This interference is often
referred to as radio–frequency or electromagnetic interference (RFI/EMI) and can be radiated through
space or conducted over interconnecting power of signal cables. In addition to electromagnetic energy,
EMC also includes possible effects from electrical fields, magnetic fields, electrostatic discharge and
disturbances in the electrical power supply.
For applicable standards refer to Chapter 2 in the Basic User Manual of the Voluson® 730Expert.
