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 because an explosion may occur.

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. Preface 1-3

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.

1.3.2

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.

1-4 Preface

1.3.3 NOTE:

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 system maintenance.
