1.2.1 Warnings
WAR NIN G
All installation operations, expansions, changes, modifications and repairs
of this product are conducted by Mindray authorized personnel.
There is high voltage inside the equipment. Never disassemble the
equipment before it is disconnected from the AC power source or the
battery.
When you disassemble/reassemble a parameter module, a patient leakage
current test must be performed before it is used again for monitoring.
The equipment must be connected to a properly installed power outlet
with protective earth contacts only. If the installation does not provide for
a protective earth conductor, disconnect it from the power line and
operate it on battery power, if possible.
Disposal of the packaging material should observe the applicable waste
control regulations and keeping it out of children’s reach.
1.2.2 Cautions
CAUTION
Make sure that no electromagnetic radiation interferes with the
performance of the equipment when preparing to carry out performance
tests. Mobile phone, X-ray equipment or MRI devices are a possible source
of interference as they may emit higher levels of electromagnetic
radiation.
Before connecting the receiver to the power line, check that the voltage
and frequency ratings of the power line are the same as those indicated on
the unit’s label or in this manual.
Protect the equipment from damage caused by drop, impact, strong
vibration or other mechanical force during servicing.
1.2.3 Notes
NOTE
Refer to operator’s manual for detailed operation and other information.

1. Input/Output connector (RS-232 connector)
This connector is used for software upgrade and DIAP communication.
2. AC power input
3. Equipotential grounding terminal:
When the equipment and other devices are to be used together, their equipotential
grounding terminals should be connected together to eliminate the potential
difference between them.
