Because of the temperature difference, water may condense inside the machine. Therefore before turning on the power, the system should be put inside the room for a while to adapt to the environment. If the outside temperature is below 10℃ or above 40℃, the system need to be put for half an hour for adapting before operation. And adapting time need to be prolonged for 1 hour for each additional temperature difference of 25℃.
2.4 Important Notes for Operation Caution: 1.
The ultrasound system should be used far away from the strong electromagnetic field (e.g. transformer). Otherwise, the system will be disturbed
2.
The ultrasound system should be used far away from high-frequency radioactive device (e.g. mobile phone). Otherwise, the system will get damaged or be affected. 2-2

Safety Precautions
To avoid the damage to the system, please don’t operate the system under the following environment: ·Environment with direct expose to sunshine ·Environment with sharp temperature change ·Environment full of dust ·Environment with vibration ·Environment near to heating source ·Environment with high humidity
4.
Please wait at least 1 minute to restart the system after it is turned off. Otherwise, it may result in a malfunction of the system.
5.
After using the probe, you may use sponge dipped by clean water to clear away the ultrasound gel remaining on the probe and then put the probe into the probe holder. Please keep the probe clean and dry.
6.
The probe must be connected or disconnected only when the system is powered off. Otherwise, it may result in a malfunction of the system.
7.
Operator can record of the examination information (including hospital and patient information etc). To ensure data safety, please back-up the information frequently ,as data stored in the system may be lost due to careless mis-operation.
8.
Please read all the operation instructions within this manual carefully.
9.
If the system is operated in a room with small space, the room temperature may rise, please keep the room well ventilated.
10. The fuse inside the system may be replaced, and only the service people or technician authorized by the manufacturer is allowed to do the replacement.

2.6 Acoustic Output and ALARA 2.6.1 Biological Effects
During ultrasound examination, the high-frequency sound wave penetrates the organism and interacts with it. Only a small part of sound energy is reflected back to the transducer to form the images, the rest energy is absorbed by the organism. When the interaction between the energy and organism reaches a certain level, it may cause the temperature rise of the tissue and the functional and structural change of the organism. This is called biological effects, which include the thermal effects and mechanical effects. Such effects are harmful to the patients, and thus better to minimize it to the acceptable level. Note: Interested users can refer to the ‘Bioeffects Considerations for the safety of Diagnostic Ultrasound, Journal of Ultrasound in Medicine, AIUM, September1988’. Or you can contact AIUM(American Institue of Ultrasound for Medicine) for more safty information related to this. 2.6.2 Thermal Effects The ultrasound energy will be absorbed by the organism during transmission, and it will transform to heat. If the heat is generated in a speed fast enough, it will increase the temperature of the tissue and become harmful, so it needs to be controlled. The main factors that affect the thermal effects are the physical characteristics of organism and the ultrasound parameters setting. Physical characteristics of organism: Some organism is very sensitive to the thermal effects, e.g. the fetus, so special care is required! Ultrasound parameters setting: The intensity of ultrasound energy is determined by ultrasound parameters like frequency, beam dimension, pulse swing, pulse duration etc. These parameters are controlled by the ultrasound scanner operator, e.g. choosing of probe type, mode, focus point position etc. Other controllable factors will also cause obvious effects, which include the movement of probe and the length of duration that the probe remains at an area. Therefore the operator should minimize the thermal effect by control these ultrasound parameters. 2.6.3 Mechanical Effects Similar with the thermal effects, the ultrasound energy will also generate mechanical effects during the interaction with the organism. The most serious one is called cavitation effect. The main factors affect this are still the organism characteristics and the controllable ultrasound parameters.

Safety Precautions
Organism characteristics include the number of tiny air bubbles inside the organism.The organism sensitivity to the cavitation effect will determine the possibility and severity of cavitation effect. Controllable ultrasound parameters include output frequency, pulse peek swing, the length of pulse duration. These parameters can be controlled by the ultrasound operator through the selection of equipment. We hope the user can have reasonable knowledge of the potential biological effects related to the frequency, intensity and scanning duration. 2.6.4 How to minimize the biological effects? Operators are suggested to take all the necessary methods and caution to avoid or minimize the risk of potential biological effects, through a better understanding of organism characteristics and more cautious control of ultrasound parameters applied. 1.
Organism characteristics The characteristics of different body parts are different, e.g. when the sound energy is absorbed during transmission, the skeleton will turn the sound energy quickly into heat, while blood and other liquid organism will transmit the sound energy to the adjacent tissue without attenuation. Special caution is required when examing a 3rd month-old fetus through abdomen area, because the ultrasound energy has not passed enough attenuation tissue before it reach the fetus. Besides, it’s also easy to hurt the fetus as it is during the important development stage. It’ll be more dangerous if the focus is made upon or around the skeleton of the fetus. Beside the fetus, any other organism which is lack of blood and not easy to transmit heat will have temperature increase with high possibility, so the operator needs to pay attention to the indication of organism change during such an examination.
2.
Controllable ultrasound parameters: Operators are suggested to reduce the risk of harmful biological effects by control of the ultrasound parameters. Try to reduce the scanning time. Users can have more training to make more experienced scanning, so the patient will have less exposure to the risk. Avoid focusing on or around sensitive tissue, e.g. eyes. If possible, change the probe type, probe position, selected frequency and scanning mode. When it is necessary to increase the acoustic output to obtain a better image, please try to increase the gain setting and other image enhancement setting firstly; if it is still necessary to increase the acoustic output, please make sure that the operator fully understand the possible effect on the organism and must carefully observe the change on real-time basis.
2.6.5 ALARA Principle ALARA means As Low As Reasonable Acheivement. Since there’s potential risk of biological effects, users are suggested to minimize the acoustic output settings to get the acceptable clinical data.
ALARA principle is widely used for X ray examination due to its potential risk. The same principle can be learned for ultrasound. Please refer to the NCRP report of ALARA, Report number 107, 12/31/1990. 2-5

Safety Precautions
For those parameters which don’t affect image quality, we suggest users to set it to make the acoustic output to the minimum. For those parameters which can increase the image quality, we suggest to set it within such a level which allows us to obtain an acceptable clinical image.
