EMC, EMI, and ESD
1-4-1 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 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.
1-4-2 Electrostatic Discharge (ESD) Prevention
WARNING WARNING
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 (TO THE
RIGHT OF THE POWER CONNECTOR).
