Preface 1-5
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 because an explosion may occur.
1.3.1 Electric Safety
WARNING:
1.
Connect the adapter 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 cable provided with this system.
2.
Before cleaning or disassembling the system, disconnect the
power cord from the socket. Otherwise, it may cause electric
shock.
3.
Make sure all connections are correct before connecting the
power supply cable during system maintenance. Otherwise
damage may result by 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 lead wires provided with the ECG
module. Otherwise it may result in electric shock.

1-6 Preface
1.3.2 Mechanical Safety
WARNING:
1.
When this system is moved, 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 transducer may cause an electric shock.
CAUTION:
1.
When move the system on the steps, fasten and fully secure
any peripheral device before moving the system, please take
care to prevent the system from toppling.
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.
Move the system only when the system is turned off or in
standby mode, otherwise damage may result to the hard disk.
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 system maintenance.
1.3.4 Others
NOTE:
For detailed operation and other information about the ultrasound system, please
refer to the operator’s manual.
