24.2 Routine Maintenance
At each routinely maintenance or the yearly maintenance, the monitor can be thoroughly inspected by qualified
personnel, including performance and safety examinations. This monitor is designed with life cycle of 5 years.
It is strongly recommended to use the product which is still within its life cycle, or it may cause inaccurate
measurement. In order to ensure its long service life, please pay attention to the maintenance.

If the hospital fails to carry out a satisfactory maintenance program about the monitor, it may get disabled
and harm the patient’s safety and health.

In case of ECG cable/lead wires damage or aging, please replace the cable or lead wires.

If there is any indication of cable and transducer damage or they deteriorate, they are prohibited from any
further use.

The Monitor is calibrated in the factory before sale, so there is no need to calibrate it during its life cycle.
Any patient simulators should not be used to validate the accuracy of blood pressure and oxygen saturation
measurement, they can only be used as functional testers to verify its precision.

The accuracy of ECG signal amplification can be verified by the built-in 1mV calibration signal.

The accuracy of pressure measurement and air leakage in pneumatic system can be verified by means of
the built-in pressure verification function and a precision pressure meter, please refer to the related chapter
in Part 2 of the user manual for detail operation.

The SpO
2
simulator cannot be used to verify the SpO
2
measuring accuracy, which should be supported by
the clinical study conducted by inducing hypoxia on healthy, non-smoking, light-to-dark-skinned subjects
in an independent research laboratory. However it is necessary for the user to use SpO
2
simulator for rou-
tine verification of precision.

Please note that the specific calibration curve (so called R-curve) should be selected when use of SpO
2
simulator, e.g. for Index 2 series SpO
2
simulator from Fluke Biomedical Corporation, please set “Make”
to “DownLoadMake: KRK”, then the user can use this particular R-curve to test the SpO
2
function of the
patient monitor with Creative oximetry technology. If the SpO
2
simulator does not contain the specific
R-curve, please ask the manufacturer for helping to download the given R-curve into the SpO
2
simulator.

The adjustable units within the monitor such as potentiometers are not allowed to adjust without permission
to avoid unnecessary failures that affect normal application.

It is recommended to use the battery once a month to ensure its power capability and long service life, and
recharge it after run out of its power capacity.
24.3 ECG Verification
The ECG signal may be inaccurate due to hardware or software problems. As a result, the ECG wave ampli-
tude becomes greater or smaller.
You can print out the square wave and wave scale and then measure the difference between them if necessary.
If the difference exceeds 5%, contact your service personnel.
24.4 Pressure Accuracy Verification
Pressure Accuracy Verification is a function to inspect the accuracy of pressure measurement by the NIBP
module inside the device. Technician or equipment manager should do pressure accuracy verification every
half year or year in order to check if the pressure measurement still conforms to the requirement of product
performance. If the deviation is beyond the declared specification, it is permitted to return it to factory for re-
pair or calibration.
Before verification, please connect the monitor to a precision pressure meter as the reference equipment like
a mercury pressure meter
