Operator Manual
1. GENERAL INFORMATION 1.1 The characteristic of the products SONEO is an electronic linear/convex ultrasound scanner with an advanced built-in digital scan converter (DSC) and a full range of multi-frequency probes from 2.5MHz to 10MHz. Take the C2-5S4 probe as an example. The center frequency of C2-5S4 is 3.5MHz and it can be converted to 2.5MHz, 3.0MHz and 5.0MHz. SONEO consists of a 10” non-interlaced monitor with larger ultrasound imaging and a backlit keyboard. The backlit keyboard allows the operator to view clearly the character on the keyboard even in a dark room. Besides, some keys will become brighter when activated. It is compatible with a video printer and equipped with a RS-232 interface for storage and handling of the image via a computer. SONEO is a full-featured and easy-operated ultrasound scanner. 1.2 Application and Warning With a varied selection of probes, SONEO can be used for examination of abdominal organs, OBS/GYN (including vagina), cardiac and thyroid gland etc. in a polymorphous hospital.
WARNING The SONEO is not applicable for ophthalmology or any examination that ultrasound beam would penetrate through eye.
1.3 Ambient Conditions This unit must be used on the following environmental conditions to ensure a safe and correct operation:

Ambient Temperature: Relative Humidity: Atmospheric Pressure:
If the operation temperature and humidity are beyond the ranges above, no correct ultrasonic images are ensured.
NOTE In case of storing the unit for a long time, the ventilation of the storage place must be considered.
Strong radiation sources or electromagnetic waves, from broadcast & TV station for instance, may cause the unit to display an image overlapped or noise. Keep the unit away from the disturbance sources. Do not place anything on the top of main unit. After use of the unit, be sure to turn off the power switch and protect the unit with the accessory dust proof cover. Whenever the unit is not used, keep the cover on since the unit is sensitive to dust. 1.4 Power Requirements The power requirements for the unit are as specified as below. Never use this unit when power supply does not meet the requirements, or the unit may possibly be damaged. Power Voltage for the Main Unit The power voltage for the main unit should be in accordance with the specification on the rear panel of the unit. The voltage fluctuation of power supply to the unit should be within the limits of ±10%. Otherwise, the unit is likely to be damaged.

Power voltage: 110V~/220V~ Frequency of the Power Supply: 50Hz/60Hz Apparent Impedance of Power Supply: 0.5Ω or less Grounding Connect the power supply after the additional protective ground connector is connected to the special ground device.
WARNING The user should wait for at least 20 seconds before switching the unit on again after power off.
1.5 Safety Classification a. This system is designed and manufactured in accordance with the Safety Requirements of IEC. To operate the unit correctly and safely, observe the following instructions: The safety protection of electronic shock is classified in Ⅰclass Type B. The safety protection of deleterious fluid is classified in IPX0. The unit should not be used in a flammable atmosphere. The unit can be operating continuously more than 8 hours. This unit needs a protective grounding device. When using it, be sure to earth it with the additional grounding device. Do not use the unit where no ground terminal is available b.

c. Adverse Effects and Precautions The SONEO, same as other diagnostic ultrasound system in the market, should be used only for clinically appropriate reasons, for the shortest period of time and at power settings as low as reasonably achievable (ALARA). The American Institute of Ultrasound in Medicine (AIUM) principle of As Low As Reasonably Achievable (ALARA) is recommended during selection of the output of ultrasound power. Try not to aim probe at the same spot in tissue for a long period of time unless it is really necessary for diagnostic purpose. This system generates acoustic power that is below pre-enactment level, which is generally considered to be safe for the respective applications. The value of ISPTA.3 under M-mode and B/M-Mode is larger than the ISPTA.3 under B-mode. The value of ISPTA.3 is the maximum when only focus M is selected. However the difference between the values of ISPTA.3 for each focus is no so much. Multi-frequency Each probe has three frequencies, including the center frequency, high frequency and low frequency. The acoustic output is decreasing from low frequency, center frequency to high frequency.

2. STRUCTURE OF THE UNIT 2.1 Main Unit Operation principle The block diagram of SONEO is shown in Fig. 2-1. Following the main unit operation principle: a. The CPU (Central Processing Unit) in the main CPU module reads the instruction from the key operation on the keyboard and issue control commands to the ultrasonic transmitter/receiver according to the instructions. b. The ultrasonic transmitter/receiver sends ultrasonic transmitting signal to the ultrasonic probe. c. The electrical signals are converted into ultrasonic signals by the transducer in ultrasonic probe, and are able to propagate in a patient’s body. d. The ultrasonic waves reflected from a patient’s body are then converted into the electrical signal by the transducer. e. The echo signals are sent to the ultrasonic transmitter/receiver, where the signals are amplified, compressed and detected. f. The detected signals are analog signals. The digital scan converter (DSC) converts them to digital signals, and further writes into a frame memory. The signals in the frame memory are read by means of television timing signals and then are converted into analog signals once again and displayed as an ultrasonic image on the monitor screen, Some image processing function, such as freezing, frame averaging, interpolation and gray scale mapping, is also realized by DSC. g. The 10” monitor receives the non-interlaced compounded video signal and display on the CRT.

NOTE If air enters between the patient body surface and the transducer place during examination, a dark spot will appear in the image. In this case, re-apply the ultrasound gel.
b. When the probe is placed on the examination region, a real-time image will immediately appear on the TV monitor screen. The orientation of the probe and the corresponding image on the screen change according to the “left/right reverse” as shown in Fig. 5-3. c. When a satisfied image is acquired on the TV monitor, press
key or
footswitch to freeze it.
● Fine adjustment of GAIN and TGC It is necessary to adjust the gain setting according to the shape of the patient and different organ to be examined. When adjusting, please refer to the following instructions. The upper portion of an image depicting the region near the body surface is too white. (near gain is too high)
Move the near field TGC sliding to the left.
The lower portion of an image depicting the inner body is too dark. (far gain is low)
Move the far field TGC sliding to the right.
