Safety Guidelines
When using the system, strictly follow the safety guidelines below to ensure the 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
multifunction 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 before you clean or uninstall the ultrasound machine,
otherwise, electric shock may result.
• 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.
