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.

A Electrical Safety Inspection

The following electrical safety tests are recommended as part of a comprehensive preventive maintenance program. They are a proven means of detecting abnormalities that, if undetected, could prove dangerous to either the patient or the operator. Additional tests may be required according to local regulations.

All tests can be performed using commercially available safety analyzer test equipment. Follow the instructions of the analyzer manufacturer.

The consistent use of a safety analyzer as a routine step in closing a repair or upgrade is emphasized as a mandatory step if an approved agency status is to be maintained. The safety analyzer also proves to be an excellent troubleshooting tool to detect abnormalities of line voltage and grounding, as well as total current loads.
