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.

4.2.2 Visual Inspection

Perform an overall inspection on the appearance of the equipment. The test is passed if the equipment has no obvious signs of damage. Follow these guidelines when inspecting the equipment:

 Carefully inspect the case, display screen, buttons, and knob for obvious signs of

damage.

 Inspect all external connections for loose connectors, bent pins or frayed cables.  Inspect all connectors on the equipment for loose connectors or bent pins.  Make sure that safety labels and data plates on the equipment are clearly legible.

Measurement validation

The SpO2 accuracy has been validated in human studies against arterial blood sample reference measured with a CO-oximeter. Pulse oximeter measurements are statistically distributed, and only about two-thirds of the measurements can be expected to fall within the specified accuracy compared to CO-oximeter measurements.

NOTE

 The SpO2 simulator can only be used to verify that the pulse oximeter

operates properly. It cannot be used to verify the accuracy of the pulse oximeter or the SpO2 sensor. To verify the accuracy, clinical tests are required.

Test Met ho d 2

Tool required:

 SpO

simulator, Index-2 recommended

Test procedure:

1. Connect the SpO

sensor to the SpO2 simulator.

2. Selected the model and manufacturer of the SpO2 module to be tested on the simulator, and set the simulator as follows: SpO

to 96% and Pulse Rate to 80 bmp.

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.
