CHAPTER 5 Maintenance and Repair
Warnings!
• The advanced circuit inside the oximeter does not require periodic calibration and
maintenance, except replacing the batteries.
• Don’t open the cover of oximeter or repair electronic circuits. Its open will cause the
damage of the device and the annulment of the guarantee.
5.1 Maintenance
Replace the batteries in a timely manner when low voltage lamp is lighted.
Clean surface of the oximeter before it is used in diagnosis for patients.
Remove the batteries if the oximeter is not operated for a long time.
It is best to store the product in -20
℃～
+55
℃
and ≤93% humidity.
Keep in a dry place. Extreme moisture may affect oximeter lifetime and may cause damage.
Dispose of batteries properly; follow any applicable local battery disposal laws.
5.2 Cleaning and Calibrating
Please use medical alcohol to clean the silicone touching the finger inside of SpO
2
probe with
a soft cloth dampened with 70% isopropyl alcohol. Also clean the being tested finger using
alcohol before and after each test.
Do not pour or spray liquids onto the oximeter, and do not allow any liquid to enter any
openings in the device. Allow the oximeter to dry thoroughly before reuse.
A functional tester cannot be used to assess the accuracy of a pulse oximeter monitor
or sensor. Clinical testing is used to establish the SpO
2
accuracy. The measured arterial
hemoglobin saturation value (SpO
2
) of the sensors is compared to arterial hemoglobin
oxygen (SaO
2
) value, determined from blood samples with a laboratory CO-oximeter. The
accuracy of the sensors in comparison to the CO-oximeter samples measured over the SpO
2
range of 70–99%. Accuracy data is calculated using the root-mean-squared (Arms value) for
all subjects, per ISO 9919:2005, Medical Electrical Equipment–Particular requirements for the
basic safety and essential performance of pulse oximeter equipment for medical use.

b) Possible problems and corresponding solutions
Problems Possible Reason Solution
SpO
2
or PR
cannot be
displayed
normally
1. Finger is not plugged
correctly
2. Patient’s Oxyhemoglobin
value is too low to be measured
1. Retry by plugging the finger
2. Attempt several times to obtain
a reading, If you are sure that no
problem exists, obtain further clinical
examination
SpO

or PR
d i s p l a y i s
unstable
1. Finger might not be plugged
deep enough
2. Finger is trembling or patient
is moving continually
1. Retry by plugging the finger
2. Urge the patient to remain still
The
Oximeter
