Safety Precautions 1-3

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

1.3.1

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.

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.

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 peripherals 3. 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. 4. 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. 5. 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. 6. 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.

1-4 Safety Precautions

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:

1.3.3 NOTE:

1.

Fasten and fully secure any peripheral device before moving the system, gently and carefully move the system to avoid falling over.

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.

Personnel Safety 1. 2. 3.

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. Only technical professionals from Mindray or engineers authorized by Mindray after training can perform maintenance.
