Safety Guidelines
When using the system, strictly follow the safety guidelines below to ensure your personal safety.
Do not use the system in the presence of flammable gases (such as anesthetic gases,
oxygen, and hydrogen) or flammable liquids (such as ethanol), as doing so may cause
an explosion.
Electrical Safety
• The power plugs of the system and its peripherals must be connected to wall
outlets with the power rating specified on the product's power rating label. The
use of a multifunctional power outlet may interfere with system grounding and
lead to overhigh leakage current. Use the power cable delivered with the
system.
• Disconnect the AC power supply before you clean or uninstall the ultrasound
machine; otherwise, electric shock may occur.
• When using peripherals not powered by the auxiliary output of the ultrasound
system or peripherals not certified by Mindray, make sure the total leakage
current of the peripherals and the ultrasound system is within the range
specified in the local electric safety standard for medical devices. For
example, GB 9706.15 requires that the touch current on the ME system parts
or between the parts in the patient environment should be within 100 μA when
the system is operating in normal state and within 500 μA when the protection
ground cable is disconnected. The user shall be responsible for determining
whether the total leakage current complies with the local standard.
• During system maintenance or assembly, make sure all the other cables are
connected properly before you connect the battery cable. Otherwise, the
system may be damaged due to hot plugging of cables.
• Do not use this system with any high-frequency electrosurgical scalpel, high-
frequency treatment equipment, or defibrillator, as doing so may cause an
electric shock to the patient.
• This system is not resistant to water. Therefore, it must be protected from any
liquid to prevent electric shock.
