installed. Philips suggests that the installer or the user of such a system consult with experts in
the field of electromagnetic compatibility and safety for guidance to ensure the safe and
effective use of the created system.
Electromagnetic Interference
Electromagnetic interference may appear in many ways on the system and depends on the
mode the equipment is operating in, the imaging control settings, the type of transducer being
used, the type of electromagnetic phenomena, and the intensity level of the phenomena.
CAUTION
When interference is present or intermittent, use caution when continuing to use the
system.
NOTE
Electromagnetic phenomena are not always present and may be transitory in nature. It may
be extremely difficult to identify the source of the interference.
NOTE
The following table describes a few typical interferences seen in imaging systems. It is
impossible to describe all manifestations of interference, because it depends on many
parameters of the transmitting device, such as the type of modulation used by the signal
carrier, the source type, and the transmitted level. It is also possible for the interference to
degrade the imaging system's performance and not be visible in the image. If the diagnostic
results are suspicious, other means should be used to confirm the diagnosis.
