Chapter 1 Safety
The operation safety is the most important concern of the designe. To ensure the safety and efficiency
of the system, the operator should read carefully about this chapter before using the system.
1.1 Safety Instructions
Read and understand all precautions in this manual before using the system.Keep this manual with the
system at all times. Periodically review the procedures for operation and safety precautions.
To maintain the performance and safety of the system, electric and mechanical safety inspections for the
system should be performed periodically by professional technicians in less than 6 months.
Do not use the system in the applications other than those listed in the intended use.Otherwise, it may
result in system damage or serious injury.
This equipment can only be used for diagnosis, cannot be used for treatment.
1.1.1 Electric Safety
Only qualified physicians or sonographers can perform ultrasound scanning on human body formedical
diagnosis.
The system can only be maintained by the person authorized or trained by the manufacturer.
The transducer is treated as the applied part.
Do not operate this system in an atmosphere containing flammable gases or liquids such
as anesthetic gases, hydrogen, and ethanol, because there is an danger of explosion.
Do not use this system at the same time with other equipment such as electric knife, defibrillator, and other
high-frequency therapy equipment. Otherwise, there is danger of electric shock.
keep the system dry, avoid beding transported to the field with a great temperature change to
prevent condensation or water droplets from resulting in short circuit.
Connect the earth conductor before powering on the system, Disconnect the grounding cable
after powering off the system. Otherwise, there is a danger of electric shock.
The AC power connector plug for the ultrasound system is a three-pin plug and should never be
adapted to any two-pin outlet. The AC power connector plug should be plugged into a hospital- grade
power outlet.
Do not place the multi-socket outlet on the floor.
Do not connect other devices to multi-socket outlet; otherwise, the rated output power may be
exceeded and failure may be resulted.
The multi-socket outlet can only be used to provide power to the recommended peripheral devices of this
system.
Select the qualified multi-socket outlet with protective grounding, and ensure its maximum output power
doesn't exceed the required one of this system.
If the non-medical electric equipment connected to the system is powered by the movable multi- socket
