EMI Limitations

Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio frequencies,
magnetic fields, and transients in the air or wiring. They also generate EMI. The Venue Fit™ ultrasound
unit complies with limits as stated on the EMC label. However, there is no guarantee that interference
will not occur in a particular setup.
NOTE: Possible EMI sources should be identified before the unit is installed, and should not be on the same
line as the ultrasound system. A dedicated line should be used for the ultrasound system.
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.
