Wireless Transmission - FujiFilm SonoSite Edge II User Manual

Cautions

Wireless transmission

The SonoSite Edge II ultrasound system contains an IEEE 802.11 transmitter that utilizes the ISM frequency
bands from 2.412 to 2.484GHz and implements two methods of transmission:
IEEE 802.11b with Complimentary Code Keying (CCK), Differential Quarternary Phase Shift Keying
(DQPSK), and Differential Binary Phase Shift Keying (DBPSK) at 16 dB
IEEE 802.11g with Orthogonal Frequency Division Multiplexing (ODFM) at 13 dBm
Safety
Medical electrical equipment requires special precautions regarding EMC and
must be installed and operated according to these instructions. Portable and
mobile RF communications equipment can affect the ultrasound system.
Electromagnetic interference (EMI) from other equipment or interference sources
could result in performance disruption of the ultrasound system. Evidence of
disruption may include image degradation or distortion, erratic readings,
equipment ceasing to operate, or other incorrect functioning. If this occurs, survey
the site to determine the source of disruption, and take the following actions to
eliminate the source(s).
Turn equipment in the vicinity off and on to isolate disruptive equipment.
Relocate or re-orient interfering equipment.
Increase distance between interfering equipment and your ultrasound system.
Manage use of frequencies close to ultrasound system frequencies.
Remove devices that are highly susceptible to EMI.
Lower power from internal sources within facility control (such as paging
systems).
Label devices susceptible to EMI.
Educate clinical staff to recognize potential EMI-related problems.
Eliminate or reduce EMI with technical solutions (such as shielding).
Restrict use of personal communicators (cell phones, computers) in areas with
devices susceptible to EMI.
Share relevant EMI information with others, particularly when evaluating new
equipment purchases which may generate EMI.
Purchase medical devices that comply with IEC 60601-1-2 EMC Standards.
Do not stack other equipment on the ultrasound system or use other equipment
in close proximity and adjacent to the ultrasound system. If stacking or using
other equipment in close proximity is unavoidable, then you must observe the
system to verify normal operation.
