EMI limitations

3-18
Ultrasound systems are susceptible to Electromagnetic
Interference (EMI) from radio frequencies, magnetic fields, and
transients in the air or wiring. They also generate EMI. The
Ultrasound system complies with limits as stated on the EMC
label. However, there is no guarantee that interference will not
occur in an installation.
Possible EMI sources should be identified before the Ultrasound
system is installed.
Electrical and electronic equipment may produce EMI
unintentionally as the result of a defect. Some of these sources
include:
• medical lasers
• scanners
• cauterizing guns
• computers
• monitors
• fans
• gel warmers
• microwave ovens
• light dimmers
• mobile phones
• in-house wireless phones (DECT phones)
• wireless computer keyboard and mouse
• air conditioning system
• High Frequency (HF) surgery equipment
• general AC/DC adapters
The presence of a broadcast station or broadcast van may also
cause interference.
See: 'EMI prevention/abatement' on page 3-19 for EMI
prevention tips.
