Application Scope, Operation Conditions, Safety and Cautions

EMC requirements, which might result in harmful interference to other device(s)
in the environment
i)
For instructions on probe disinfection and protection, follow the description in
4.2.9.
j)
It is prohibited to scan eyes with the probe. Keep the acoustic power as low as
reasonably achievable (ALARA). Scan the body only in a period required for
making the diagnosis, rather than scan the body for a long time. An extended
scan might result in harm to personal health. Provided that clinical indications are
required, the system operator shall be fully acquainted with acoustic output or be
accessible to relevant thermal index. The probe, when exposed in the air and
noticeable heat from the probe itself, should not be applied to trans-vaginal exam.
Pay special attention to minimize exposed acoustic power and exposure period
when used on an embryo or a fetus.
k) To ensure safety, only qualified ultrasound coupling gel compliant to relevant
standards shall be applied.
l)
During examination, in case images are interfered by an AC noise (hum-hum)
due to the patient, put a shield sheet between the body and the bed as shown in
Fig.1-1, and connect the sheet to the equipotential terminal of the main unit. The
hum-hum interference noise can be eliminated.
m) The system operator should not touch any tangible metal parts of any electronic
device in the patient environment and the patient at the same time.
n) The system does not provide special protection functions or measures for use
with high frequency surgery equipment. The user should be cautious of such
application.
o) Shut down the system in correct procedures, otherwise it might result in system
data loss or system failure.
p) Except for the USB port, do not disconnect the system or any other peripheral
