Application Scope, Operation Conditions, Safety and Cautions
1-3
IEC60601-1-1; the removable multi-jack socket for the system shall comply with
requirements of IEC60601-1-1 Appendix EEE;
h) Do not place the removable multi-jack socket on the ground, otherwise, it may result in
danger.
i) The maximum load capacity of the removable multi-jack socket shall not be less than
the total load of all the devices consisting of the system, or it may result in danger.

Tip
】
: In regions where mains supply is not stable, it is recommended to use
power supply from a stabilizer with output power of 250VA, so as to avoid
damage to the system due to mains fluctuation.
1.4 Safety
The system is designed and manufactured in compliance with the international standard
IEC 60601-1:2005 To operate it safely and correctly, please follow the instructions below:
a)
This system is not explosion-proof. Do not operate it in a flammable or easy
explosive environment(e.g. in the presence of anesthetics, oxygen or hydrogen);
b)
The system is not waterproof. Never allow water or other liquid to drip on to the
system;
c)
The system needs a protective grounding device. Its power cable should be
connected to a grounding socket. If the system is powered by a power supply
without grounding, its equipotential terminal must be connected to the
equipotential terminal on another grounded system or an additional grounded
device. Do not use the system where there is no ground terminal is available;
d)
Biological safety: the same as other diagnostic ultrasound products, the material
used for this products is proved to be innocuous through a long-period trial. It will
not result in allergy or stimulation to human body and skin;
e)
Ultrasound safety: ALARA

should be observed.
Patients should always be exposed to the lowest practical transmit power levels
for the shortest possible time. Freeze the system and keep the probe away from
the patient if no scanning is done. Do not examine the patient with the probe on a
