Safety precautions
In order to prevent the damage caused by improper use, please observe the following safety
precautions.
Safety precautions
Warning
1. The user should according to the provisions in this manual operation, the manufacturer does not
assume in violation of the instructions may cause a variety of security risks.
2. The medical device is not for family using, it can be used by a qualified physician only.
3. Do not use the probe to scan the patient’s eyes or cause the beam through the eyes in any way.
4. Ultrasound under the condition of low power is safe, in the case of high power or irradiation for a
long time, its security has not been fully confirmed. So, Use the instrument physicians should use the
lowest possible sound power, reasonable choose detection parts and controls the scanning time, only to
make a diagnosis required time is limited, to avoid damaging on the patients.
5. In the embryo or fetus examine, scanning should pay special attention to reduce the radiation
sound power and irradiation time. Avoid heat generated by the potential harm on embryo or fetus.
6. The probe can not be fixed in the same part of patients to scan for a long time.
7. The instrument can't use with cardiac defibrillator and high-frequency surgery or treatment
equipment, to prevent electric shock or damage to the instrument on patients.
8. The instrument is forbidden to use under the follows environment such as the air mixture
flammable gas, mixed with oxygen or nitrous oxide of flammable gas and other combustible gas to
prevent the risk of explosion.
9. The instrument cannot be used for patients with heart.
10. If it can detect the hot ultrasonic probe in the naturally air, it cannot be used for the vagina examine.
11. The instrument is not applicable to gas organs such as the stomach, intestine, lung and other
organs; Can't have wounds or acute inflammation to detect, in order to avoid cross infection.
12. Power supply must comply with the provisions of the safe electricity, if the power protection
grounding terminals is not conforming to the rules, using instrument is strictly prohibited. Otherwise it
will cause personal injury accidents.
13. Should check the power cord of the instrument frequently, if found damage such as fracture
should be replaced immediately.
14. Should inspect the probe frequently, if found there is any breakage, crack on the surface of cable
or probe, should be immediately shut down and stop using.
15. Before cleaning host and probe appearance, in order to avoid the accident, should unplug the
power cord and cut off power supply net completely.

Safety precautions
Careful
1. Should prevent the probe far away from the sharp, hard object, it is forbidden to collision probe
acoustic window, otherwise it will cause damage of the probe.
2. Probe for a long time can cause fever, during the suspension diagnosis, should press the "frozen"
button to make the probe to stop working.
3. The probe’s waterproof grade is IPX7,and the part of the probe which is soaked in the water
can not surpass 5mm than the acoustic window.
4. Use unqualified coupling agent can make the probe acoustic window from corrosion and damage
should be used for medical ultrasonic coupling agent.
5. Only used in the probe head coupling agent, carefully clean after use.
6. Probe is forbidden to be heated. If the probe temperature is lower than the room temperature, it
can be heated naturally before use.
7. Do not insert or take down the probe in the electric situation.
8. In using process, it is strictly prohibited to cover the heat emission hole of the instrument.
9. Please do not open the instrument shell by oneself, in order to avoid possible electric shock risk.
Any instrument maintenance and upgrade must be authorized by the manufacturer, training and service
personnel.
10. Sundry, water cup, etc. are not permitted on the operation panel.
11. The instrument can only use the probe of manufacturer configuration; otherwise it will cause
damage of equipment.
12. In using process, if an exception occurs, please shut down immediately.
Attention
1. Power supply circuit of the instrument and the bearing capacity of the power supply socket range
is 110V~240 V / 1.5 A. If use extended patch panel, please choose a product which with the safety
certification.
2. When using should be far away from the strong electric field, strong magnetic field devices and
high voltage equipment.
3. If the instruments used in conjunction with other medical equipment, please consult manufacturer,
shall be carried out under the guidance of manufacturer.
4. Do not use the unspecified accessories (such as insurance and protect the earth wire, etc.), in order
to avoid adverse impact on performance and security in the device.
5. After shutdown the instrument every time, should wait for at least 2 ~ 3 minutes to start up again,
so as not to damage the instrument.
6. The screen is fragile, please do not hit, in order to avoid break.
