System Preparation  3-1 
3  System Preparation 
WARNING: 
1. 
Do not connect the three-wire cable of the system with a two-wire 
plug without protective grounding; otherwise, electric shock may 
result. 
 
2. 
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. 
3. 
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. 
 
4. 
DO NOT use power supply of different phases to power peripherals, 
like power supply of air-conditioning. 
 
5. 
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.
 
 
3.1  Moving/Position the System 
Please read and understand the safety precautions before placing the system to ensure safety for both 
operator and devices. 
If the ultrasound system is configured with the central brake system: 
1.  Switch off the power, and pull out the plug. 
2.  Disconnect all cables from the off-board peripheral devices (printer, recorder, etc.) 
3.  Unlock the central brake pedal and reset the green pedal of the double-lock caster; hold the handle 
to move the system. 
4.  When you move the system to a desired location, press down the central brake pedal and red 
pedal of the double-lock caster to lock the four casters. 
If the ultrasound system is not configured with the central brake system: 
1.  Switch off the power, and pull out the plug. 
2.  Disconnect all cables from the off-board peripheral devices (printer, recorder, etc.) 
3.  Unlock the four casters; hold the handle to move the system. 
4.  When you move the system to a desired location, lock the four casters.
