pushed from the sides, it may fall down and cause injury.
(3) When the system is moved over a sloped surface, it must be
moved slowly by two persons. Otherwise, the system may
slide unexpectedly and cause a serious injury.
(4) Do not sit on the system.
The system may move, causing you to lose your balance
and fall.
(5) Do not place any objects on top of the monitor. They may
fall, causing injury.

S-5
(6) Confirm that the peripheral units are secured before you
move the system. Otherwise, the peripheral units may fall
and cause injury.
(7) When the system is moved over a step, exercise caution to
protect the system from falling. When holding the system at
the bottom to help move it over a step, take special care to
prevent hand injuries.
4．Do not vibrate the equipment excessively (when moving the
equipment); otherwise the mechanical parts (such as casters) may
be damaged. If the system is often moved on a bumpy floor, contact
the Mindray sales office, customer service department or
representative.
5. Do not connect this system to outlets with the same circuit
breakers and fuses that control the current of devices such as
life-support systems. If this system malfunctions and generates an
overcurrent, or when there is an instantaneous current at power
ON, the circuit breakers and fuses of the building’s supply circuit
may be tripped.
6．Always keep the machine dry. Avoid transporting this machine
quickly from the cold place to the warm place, otherwise
condensation or water drops may be formed, which will cause short
circuit.
7．If the circuit breaker is tripped or the fuse is blown, it indicates that
the machine or the peripheral devices have problems. In these
