System Preparation
WARNING:
1.
Do not connect the system's three-wire cable with a two-wire
plug without protective grounding. This may lead to electric
shock.
2.
Connect the power plug of this system to wall receptacles that
meet the ratings indicated on the nameplate. If adapters or
multifunctional receptacles are used, it may cause the leakage
current to exceed the safety requirements.
3.
Within 1.5 meters of the patient, connect peripherals to an
auxiliary power outlet which is capable of isolation protection,
or power peripherals by an auxiliary output cable or isolation
transformer which complies with IEC 60601-1 in Chapter 16 or a
power input of the same safety level.
4.
DO NOT use different-phase power supplies to power
peripherals.
5. When using peripherals which are not powered by the ultrasound
system's auxiliary output, or peripherals other than those permitted
by Mindray, ensure the overall leakage current of peripherals and the
ultrasound system meets the requirement of the local medical device
electrical regulations (e.g., the enclosure leakage current should be
no more than 500uA as per IEC 60601-1 in Chapter 16), and the
responsibility is held by the user.
3.1 Move/Position the System
Read and understand the safety precautions before positioning the system to ensure the safety of
both the operator and the devices.
1. Switch off the power, and pull out the plug.
2. Disconnect all cables from off-board peripheral devices (printer, recorder, etc.).
3. Release the four casters and hold the handle to move the system.
4. When moving the system to a desired location, lock the four casters.
CAUTION:
1. Maintain a generous, free air flowing space around the back and
both sides of the system. Not doing so may result in failure due to
the increased rise in the system's operating temperature.
2. Pay extra attention when moving the system on a sloping surface.
Do not move it on a surface with a slope of more than 10° to avoid
the system toppling.
