Mindray DC-33 - Safety Precautions

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 IEC 60601-
1-1 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 IEC 60601-1-1), 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. Otherwise, system failure and electric shock may
result.
8.
This system is not water-proof. Do not use this system in any
place where water leakage may occur. If any water is sprayed
on or into the system, electric shock may result. If water is
accidentally sprayed on or into the system, contact Mindray
Customer Service Department or sales representative.
