Section 1-7
EMC, EMI, and ESD
1-7-1 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.
1-7-2 CE Compliance
The Vivid S5 N and Vivid S6 N ultrasound scanners conform 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 S5 N or Vivid S6 N User Manual.
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.
1-7-3 Electrostatic Discharge (ESD) Prevention
1-7-4 General Caution
WARNINGWARNING
DO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING THE
NECESSARY ESD PRECAUTIONS.
1. ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP, TO THE ADVISED
ESD CONNECTION POINT LOCATED ON THE REAR OF THE SCANNER (NEAR THE
POWER CONNECTOR).
2. FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC SENSITIVE
EQUIPMENT.
WARNINGWARNING
RISK OF ELECTRICAL SHOCK, SYSTEM MUST BE TURNED OFF. AVOID ALL
CONTACT WITH ELECTRICAL CONTACTS, CONDUCTORS AND COMPONENTS.
ALWAYS USE NON-CONDUCTIVE HANDLES DESIGNED FOR THE REMOVAL AND
REPLACEMENT OF ESD SENSITIVE PARTS. ALL PARTS THAT HAVE THE POTENTIAL
FOR STORING ENERGY MUST BE DISCHARGED OR ISOLATED BEFORE MAKING
CONTACT.
CAUTION
Any changes to accessories, peripheral units or any other part of the system must be approved
by the manufacturer. Ignoring this advice may compromise the regulatory approvals obtained
for the product.
