General
recommendations Ultrasound instruments are susceptible to Electromagnetic
Interference (EMI) from radio frequencies, magnetic fields, and
transients in the air or wiring. They also generate EMI. The
Invenia ABUS 2.0 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 Invenia
ABUS 2.0 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
• 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.
