Safety Precautions  1-3 
1.4  Safety Precautions 
Please observe the following precautions to ensure patient and operator’s safety when using this 
system. 
DANGER: 
Do not operate this system and probes in an atmosphere containing 
flammable gasses or liquids such as anesthetic gasses, hydrogen, and 
ethanol, because there is danger of explosion.
 
 
WARNING: 
1. 
Do connect the power plug of this system to wall receptacles 
that meet the ratings indicated on the rating nameplate. If 
adapters or multifunctional receptacles are used, it may cause 
the leakage current to exceed the safety requirement.
 
2.  In the environment that patient is 1.5 meters around, connect 
peripherals to the auxiliary power outlet which is capable of 
isolation protection, or power the peripherals by auxiliary output 
cable or isolation transformer complied with IEC60601-1 or the 
power input of the same safety level.
 
3.  DO NOT use power supply of different phases to power 
peripherals, like power supply of air-conditioning.
 
4.  When using peripherals not powered by the auxiliary output of 
the ultrasound system, or using peripherals other than permitted 
by Mindray, make sure the overall leakage current of peripherals 
and the ultrasound system meets the requirement of the local 
medical device electrical regulation (like enclosure leakage 
current should be no more than 500uA of IEC60601-1), and the 
responsibility is held by the user.
 
5. 
Connect the grounding conductor before turning ON the system. 
Disconnect the grounding cable after turning OFF the system. 
Otherwise, electric shock may result.
 
6. 
For the connection of power and grounding, follow the 
appropriate procedures described in this operator’s manual. 
Otherwise, there is risk of electric shock. Do not connect the 
grounding cable to a gas pipe or water pipe; otherwise, improper 
grounding may result or a gas explosion may occur.
 
 
7. 
Before cleaning the system, disconnect the power cord from the 
outlet. System failure and electric shock may result.
 
 
8. 
This system is not water-proof designed. Do Not use this system 
in any place where water or any liquid leakage may occur. If any 
water is sprayed on or into the system, electric shock may result 
or the system may be damaged. If water is accidentally sprayed 
on or into the system, contact Mindray Customer Service 
Department or sales representative.
 
 
9. 
DO NOT use a probe that has a damaged, scratched surface, or 
exposed wiring of any kind. Immediately stop using the probe 
and contact Mindray Customer Service Department or sales 
representative. There is risk of electric shock if using a damaged 
or scratched transducer.
