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.

leakage test:
1. In the [Patient Demographics] menu, set [Patient Category] to [Adult].
2. Connect the NIBP cuff to the NIBP connector on the monitor.
3. Apply the cuff to the cylinder as shown below.

After about 20 seconds, the monitor will automatically deflate. This means the test is complete. If no message is displayed in the NIBP parameter area, it indicates that the system has no leakage. If the message [
NIBP Pneumatic Leak] is displayed, it indicates that the
system may have a leak. Check the tubing and connections for leakages. Ensure that the tubing and connections are all correct, perform a leakage test again. If the problem persists, contact our Technical Support Department.
You may also perform a manual leakage test:
1. Perform steps 1 to 4 in the NIBP Accuracy Test section.
2. Raise the pressure in the rigid vessel to 250 mmHg with the manometer bulb. Then, wait for 5 seconds to allow the pressure to stabilize.
3. Record the current pressure value, wait 60 seconds and record the pressure again.
4. Compare the two pressure values and verify the difference is 6mmHg or less.

NIBP Accuracy Test
Tool required:
T-shape connector Appropriate tubing
Manometer bulb
Rigid Vessel with volume 500 ± 25 ml Reference manometer (calibrated with accuracy equal to or better than 0.75
mmHg)
Follow this procedure to perform the accuracy test:
1. Connect the equipment as shown below.
Monitor
Standard sphygmomanometer
Connector for NIBP cuff
Manometer bulb
Appropriate tubing
Rigid Vessel
2. Before inflation, check that the reading of the manometer is 0. If not, turn off the manometer bulb to let the whole airway open to the atmosphere. Turn on the manometer bulb after the reading is 0.
3. Select [Main][Maintenance >>][User Settings>>]Enter required password→[
Module Maintenance >>][NIBP Accuracy Test].
4. Check the manometer values and the monitor values. Both should be 0 mmHg.
5. Raise the pressure in the rigid vessel to 50 mmHg with the manometer bulb. Then, wait for 10 seconds to let the measured values become stable.
6. Compare the manometer values with the monitor values. The difference between the manometer and displayed values should be ± 3 mmHg. If it is greater than ± 3 mmHg, contact Mindray Technical Support.
7. Raise the pressure in the rigid vessel to 200 mmHg with the manometer bulb. Then, wait for 10 seconds to let the measured values become stable. Repeat step
6.
NOTE
You can use an NIBP simulator to replace the manometer bulb and the
reference manometer to perform the test.
