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 h
ydrogen or explosive fluid such as
ethanol. Otherwise, an explosion may occur.

XI
Electric safety
WARNING:
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.
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 using peripherals other than permitted by Mindray,
make sure the overall leakage current of pe
ripherals and the ultrasound
system meets the requirement of the local medical device electrical regulation
(like enclosure leakage current should be no more than 500uA of IEC 60601-
1-1), and the responsibility is held by the user.
In maintenance or asse
mbly/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.

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.
This system is not water-proof. If any water is sprayed on or into the system,
electric shock may result.
CAUTION:
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.

Avoid electromagnetic radiation when perform performance test on the
ultrasound system.

In an electrostatic sensitive environment, don’t touch the device directly.
Please wear electrostatic protecting gloves if necessary.
You should use the ECG leads provided with the ECG module. Otherwise it
may result in electric shock.
The maximum output power of the output interface of the trolley is 240 VA.
Mechanical safety
WARNING: 
When moving the system, you should first fold the LCD display, disconnect
the system from other devices (including probes) and disconnect the system
from the power supply.
Do not subject the transducers to knocks or drops. Use of a defective probe
may cause electric shock to the patient.

XII
CAUTION: Do not expose the system to excessive vibration (during the transportation)
to avoid device dropping, collision, or mechanical damage.
When you place the system on the trolley and move them together, you must
secure all objects on the trolley to prevent them from falling. Otherwise you
should separate the system from the trolley and move them individually.
When you have to move the system with the trolley upward or downward the
stairs, you must separate them first and then move them individually.

Do not move the ultrasound system if the HDD indicator is green, sudden
shake may cause the HDD in damage.
When moving the trolley with mounted system, protect the connector of the
power adapter from damage due to collision with other objects.
Personnel safety
Note: The user is not allowed to open the covers and panel of the system, neither device
disassemble is allowed.
To ensure the system performance and safety, only Mindray engineers or engineers
authorized by Mindray can perform maintenance and check.
Only technical professionals from Mindray or engineers authorized by Mindray after
training can perform maintenance.
Others
Note: For detailed operation and other information about the ultrasound system, please refer
to the operator’s manual.

Battery capacity 6600 mAh (per battery)
1.1.2.2 Requirements of Regulator
Due to the difference of the power supply stability of different districts, please advise the user to adopt a
regulator of good quality and performance such as an on-line UPS.
1.1.2.3 Grounding Requirements
The power cord of the system is a three-wire cable. The grounding protective terminal should be
connected with grounding protective cable of the power supply system. Make sure that the protective
grounding works normally.
WARNING:
DO NOT connect this system to outlets with the same circuit breakers and fuses
that control the current of devices such as life-
support systems. If this system
malfunctions and generates an over-
current, or when there is an instantaneous
current at power ON, the circuit breakers and fuses of the building’s supply circuit
may be tripped.
1.1.3 EMI Limitation
Ultrasound devices are susceptible to Electromagnetic Interference (EMI) from radio frequencies,
magnetic fields, and transient in the air wiring. They also generate EMI. Possible EMI sources should be
identified before the unit is installed.
These sources include: medical lasers, scanners, monitors, cauterizing guns, etc. Besides, other devices
that may result in high-frequency electromagnetic interference such as mobile phone, radio transceiver
and wireless remote control toys are not allowed to be presented or used in the room. Turn off those
devices to make sure the ultrasound system can work in a normal way.
