WARNING
Electrosurgical units (ESUs) and other devices intentionally introduce radio frequency
electromagnetic fields or currents into patients. Because imaging ultrasound frequencies are
coincidentally in the radio frequency range, ultrasound transducer circuits are susceptible to
radio frequency interference. While an ESU is in use, severe noise interferes with the black-
and-white image and completely obliterates the color image.
WARNING
To avoid risk of a burn hazard, do not use transducers with high-frequency surgical
equipment. A burn hazard may result from a defect in the high-frequency surgical neutral
electrode connection.
WARNING
Using cables, transducers, and accessories other than those specified for use with the
system may result in increased emissions from, or decreased immunity of, the system.
CAUTION
Use of the system in the presence of an electromagnetic field can cause momentary
degradation of the ultrasound image. When interference is present or intermittent, use
caution when continuing to use the system. If interference occurs often, review the
environment in which the system is being used to identify possible sources of radiated
emissions. These emissions could be from other electrical devices used within the same
room or an adjacent room. Communication devices such as cellular phones and pagers can
cause these emissions. The existence of radio, TV, or microwave transmission equipment
located nearby can cause emissions. In cases where EMI is causing disturbance, it may be
necessary to relocate your system.
