Cables, transducers, and accessories connected to the system may affect its
immunity to the electromagnetic phenomena listed in Table 6-6. Use only cables,
transducers, and accessories listed in “Approved Cables, Transducers, and Acces-
sories for EMC” on page 128 to minimize the change of performance degradation
of the ultrasound system due to these types of electromagnetic phenomena.
