artifacts (vertical lines, excessive noise in image, etc.) may appear on the ultrasound image. To
eliminate these artifacts caused by an EFT condition, the operator should either:
• Disconnect the system from the power source by unplugging the power cord from the tablet, and
run the system on its internal battery.
or
• Unplug the power cord from the wall and move to a different power source that is not
experiencing this condition.
2.2.3 Electromagnetic Interference (EMI)
Medical electrical equipment such as the system requires special precautions regarding
electromagnetic compatibility, and must be installed and put into service according to the following
electromagnetic tables.
2.2.3.1 All Equipment

RF Emissions CISPR 11 Group 1
The T3300 Diagnostic Ultrasound System uses RF
energy only for its internal function. Therefore, its
RF emissions are very low and are not likely to
cause any interference in nearby electronic
equipment.
RF Emissions CISPR 11 Class B The T3300 Diagnostic Ultrasound System is
suitable for use in all establishments, including
domestic, and those directly connected to the
public low-voltage power supply network that
supplies buildings used for domestic purposes.
