2-2-3 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 LOGIQ™ 180 complies
with limits as stated on the EMC label. However there is no guarantee that interference will not occur in
a particular installation.
Possible EMI sources should be identified before the unit is installed.
Electrical and electronic equipment may produce EMI unintentionally as the result of a defect. These
sources include:
• medical lasers,
• scanners,
• cauterizing guns,
• computers,
• monitors,
• fans,
• gel warmers,
• microwave ovens,
• light dimmers
• portable phones.
The presence of a broadcast station or broadcast van may also cause interference.
