1.2 Indication for Use
The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through
finger. The product is suitable for being used in family, hospital, oxygen bar, community healthcare,
physical care in sports (It can be used before or after doing sports, and it is not recommended to use the
device during the process of having sport) and etc.

1.4 Precautions
1.4.1 Attention
Point out conditions or practices that may cause damage to the device or other properties.
Before using the device, make sure that it locates in normal working state and operating environ-
ment.
In order to get a more accurate measurement, it should be used in a quiet and comfortable environ-
ment.
When the device is carried from cold or hot environment to warm or humid environment, please do
not use it immediately, wait four hours at least is recommended.
If the device is splashed or coagulated by water, please stop operating.
DO NOT operate the device with sharp things.
High temperature, high pressure, gas sterilizing or immersion disinfection for the device is not per-
mitted. Refer to User Manual in the relative chapter (6.1) for cleaning and disinfection. Please turn
off the device and disconnect it from the power.
The device is suitable for children and adult.
The device may not be suitable for all patients, if you can’t get a satisfactory result, please stop using
it.
Data averaging and signal processing generate delay on displayed and transmitted SpO
2
value and
alarm signal generation. The data update period is shorter than 30 s, the time for obtaining dynamic
average values will increase, which is arisen from signal degradation, low perfusion or other interfer-
ence, it depends on the PR value.
The device has 3-year service life, date of manufacture: see the label.
To further detect the alarm of individual measurement parameter, measure and check oneself or with
a simulator, adjust the alarm limit setting and check whether the correct alarm can be triggered.
This device has the function of alarm, patients can check on this function according to chapter 5.3 as
a reference.
The device has the function of limits alarm, when the measured data is beyond the highest or lowest
limit, the device would start alarm automatically on the premise of the alarm function is on.
The device has the function of alarm, this function can either be paused, or closed for good. This
function could be turned on through menu operation if you need. Please check the chapter 5.3 as a
reference.
The maximum temperature at the SpO
2
probe -tissue interface should be less than 41℃ which is
measured by the temperature tester.
During measuring, when abnormal conditions appear on the screen, please pull out your finger and
reinsert it to measure again.
If some unknown error appears during measuring, press “RESET” button to reset it.
Do not contort or drag the wire of the device.
The plethysmographic waveform is not normalized, as a signal inadequacy indicator, when it is not
smooth and stable, the accuracy of the measured value may degrade. When it tends to be smooth
and stable, the measured value read is the optimal and the waveform at this time is also the most
standard.
