CAUTION: 1．Precautions concerning clinical examination techniques (1) This system can only be used by medical personnel fully trained in clinical examination techniques. (2) This manual does not describe clinical examination techniques. Selection of the proper clinical examination technique must be based on specialized training and clinical experience. 2．Malfunctions due to radiowaves (1) Use of radiowave-emitting devices in the proximity of this kind of medical electronic system may interfere with its operation. Do not bring or use devices which generate radio waves, such as cellular telephones, transceivers, and radio controlled toys, in the room where the system is installed. (2) If a user brings a device which generates radio waves near the system, he must be instructed to immediately turn OFF the device. This is necessary to ensure the proper operation of the system. 3． Precautions concerning installation and movement of the system (1) Be sure to install the system on a level floor and lock the casters. Otherwise, the system may move, and injure the patient. (2) Do not push the system from the sides. If the system is pushed from the sides, it may fall down and cause injury. (3) When the system is moved over a sloped surface, it must be moved slowly by two persons. Otherwise, the system may slide unexpectedly and cause a serious injury. (4) Do not sit on the system. The system may move, causing you to lose your balance and fall. (5) Do not place any objects on top of the monitor. They may fall, causing injury.

S-4

(6) Confirm that the peripheral units are secured before you move the system. Otherwise, the peripheral units may fall and cause injury. (7) When the system is moved over a step, exercise caution to protect the system from falling. When holding the system at the bottom to help move it over a step, take special care to prevent hand injuries. 4．Do not vibrate the equipment excessively (when moving the equipment); otherwise the mechanical parts (such as casters) may be damaged. If the system is often moved on a bumpy floor, contact the Mindray sales office, customer service department or representative. 5. 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 overcurrent, or when there is an instantaneous current at power ON, the circuit breakers and fuses of the building’s supply circuit may be tripped. 6． Always keep the machine dry. Avoid transporting this machine quickly from the cold place to the warm place, otherwise condensation or water drops may be formed, which will cause short circuit. 7． If the circuit breaker is tripped or the fuse is blown, it indicates that the machine or the peripheral devices have problems. In these cases, the user cannot repair by him but contact the Mindray sales office, customer service department or representative. 8． There is no risk of high-temperature burns during routine ultrasound examinations, even if, due to environment temperature and exam modes, the surface temperature of the transducer exceeds the body temperature of the patient. To prevent high-temperature burns, do not apply the transducer to the same region on the patient for a long time. Apply the transducer only for as long as required time for diagnosis. 9．After the sterilization or disinfection of accessories, chemicals must be washed out or gases must be discharged thoroughly from the accessories. Remaining residual chemicals or gases will not only result in damage to the accessories but also can be harmful to human bodies.
