EMC, EMI, and ESD
1-5-1
Electromagnetic Compatibility (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 to interference from its environment,
or when the device produces unacceptable levels of emission. 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 or 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.
The Vivid i n/ Vivid q N system and the SafeLock Cart should be operated at a distance of more
than 15 feet from any magnetic field.
1-5-2
CE Compliance
The Vivid i n and Vivid q N portable ultrasound scanner conforms to all applicable conducted and
radiated emission limits and to immunity from electrostatic discharge, radiated and conducted RF fields,
magnetic fields and power line transient requirements.
For applicable standards refer to the Safety Chapter in the Vivid i
NOTE:
For CE Compliance, it is critical that all covers, screws, shielding, gaskets, mesh and clamps are in good
condition and installed tightly without skew or stress. Proper installation following all comments noted
in this service manual is required in order to achieve full EMC performance.
1-5-3
Electrostatic Discharge (ESD) Prevention
CAUTION:
TAKING THE NECESSARY ESD PRECAUTIONS:
1.ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP CONNECTED TO THE
BOTTOM COVER WHENEVER YOU OPEN THE SYSTEM FOR MAINTENANCE.
2.FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC SENSITIVE
EQUIPMENT.
