1.3 Safety Precautions
Please read the following precautions carefully to ensure the safety of the patient and the
operator when using the probes.
DANGER
Do not operate this system in an atmosphere containing flammable
or explosive gases such as anesthetic gases, oxygen, and
hydrogen or explosive fluid such as ethanol because an explosion
may occur.

1-4 Safety Precautions
1.3.1 Electric safety
WARNING:
1.
Connect the power plug of this system and power plugs of the
peripherals to wall receptacles that meet the ratings indicated
on the rating nameplate. Using a multifunctional receptacle
may affect the system grounding performance, and cause the
leakage current to exceed safety requirements. Use the power
cord accompanied with the system provided by Mindray.
2.
Disconnect the AC power before you clean or uninstall the
ultrasound machine, otherwise, electric shock may result.
3.
In maintenance or assembly/disassembly, make sure other
cables are connected well before the battery connecting cable
is connected, otherwise the system may be damaged due to
hot-plug.
4.
Do not use this system simultaneously with equipment such
as an electrosurgical unit, high-frequency therapy equipment,
or a defibrillator, etc.; otherwise electric shock may result.
5.
This system is not water-proof. If any water is sprayed on or
into the system, electric shock may result.
CAUTION:
1.
DO NOT connect or disconnect the system’s power cord or its
accessories (e.g., a printer or a recorder) without turning OFF
the power first. This may damage the system and its
accessories or cause electric shock.
2.
Avoid electromagnetic radiation when perform performance
test on the ultrasound system.
3.
In an electrostatic sensitive environment, don’t touch the
device directly. Please wear electrostatic protecting gloves if
necessary.
4.
You should use the ECG leads provided with the ECG module.
Otherwise it may result in electric shock.
1.3.2 Mechanical safety
WARNING:
1.
Before moving the system, please hold the handle. If other parts
of the system are held, it may cause damage due to the
abnormal force. Do not push the system from the left/right side;
otherwise, it may be toppled over.
2.
Do not subject the transducers to knocks or drops. Use of a
defective probe may cause electric shock to the patient.
CAUTION:
1.
Fasten and fully secure any peripheral device before moving
the system, gently and carefully move the system to avoid
falling over.

Safety Precautions 1-5
2.
Do not expose the system to excessive vibration (during the
transportation) to avoid device dropping, collision, or
mechanical damage.
3.
Please install the system on a flat plane with the four casters
locked. Otherwise, damage may be resulted by accidental
moving.
4.
Pay extra attention when moving the system on a sloping
ground, do not move it on a more than 10°-sloped plane to avoid
system toppling.
5.
Move the system ONLY WHEN the system is shut down or in
standby status, otherwise the system hardware disk may be
damaged.
1.3.3 Personnel Safety
NOTE:
1.
The user is not allowed to open the covers and panel of the system, neither
device disassemble is allowed.
2.
To ensure the system performance and safety, only Mindray engineers or
engineers authorized by Mindray can perform maintenance.
3.
Only technical professionals from Mindray or engineers authorized by Mindray
after training can perform maintenance.
1.3.4 Other
NOTE:
For detailed operation and other information about the ultrasound system, please
refer to the operator’s manual.
