Electromagnetic Immunity
The ultrasound system is intended for use in the electromagnetic environment
specified in Table 6-6. The customer or the user of the ultrasound system should
ensure that it is used in such an environment.
NOTES
• The guidelines specified in Table 6-6 may not apply in all situations. Electro-
magnetic propagation is affected by absorption and reflection from structures,
objects, and people.
• U
T
is the AC mains voltage before application of the test level.
• At 80 and 800 MHz, the separation distance for the higher frequency range
applies.
