ment.
In order to get a more accurate measurement, it should be used in a quiet and comfortable environ-
ment.
When it is carried from cold environment to warm or humid environment, please do not use it imme-
diately.
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 before cleaning and disinfection.Please take out the internal battery before cleaning and
disinfection.
The device is suitable for children and adult.
The device may not be suitable for all users, if you can't get a satisfactory result, please stop using
it.
Data averaging and signal processing have a delay in the upgrade of SpO2 data values. When
the data update period is less than 30 seconds, the time for obtaining dynamic average values will
increase, which is arisen from signal degradation, low perfusion or other interference, it depends on
the PR value.
The device has 3-year service life, date of manufacture: see the label.
This device has the function of prompting, users can check on this function according to chapter
5.5.1 as a reference.
The device has the function of limits prompting, when the measured data is beyond the highest or
lowest limit, the device would start prompting automatically on the premise of the prompting function
is on.
The device has the function of prompting, this function can either be paused, or closed (default set-
ting) for good. This function could be turned on through menu operation if you need. Please check
the chapter 5.5.1as a reference.
The device hasn't low-voltage prompt function, it only shows the low-voltage, please change the
battery when the battery voltage is used up.
The maximum temperature at the SpO2 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, remove the battery to terminate operating.
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.
If necessary, please visit our official website to get the information about SpO2 probe that can be
used with this device.
If the device or component is intended for single-use, then the repeated use of these parts will pose
risks on the parameters and technical parameters of the equipment known to the manufacturer.
If necessary, our company can provide some information (such as circuit diagrams, component lists,
illustrations, etc.), so that the qualified technical personnel of the user can repair the device compo-
nents designated by our company.
The measured results will be influenced by the external colouring agent (such as nail polish, colour-
ing agent or color skin care products, etc.), so don't use them on the test site.
As to the fingers which are too cold or too thin or whose fingernail is too long, it may affect the meas-
ured results, so please insert the thicker finger such as thumb or middle finger deeply enough into
the probe when measuring.
The finger should be placed correctly (see Attached figure 6), as improper installation or improper
contact position for sensor will influence the measurement.
The light between the photoelectric receiving tube and the light-emitting tube of the device must
pass through the subject's arteriole. Make sure the optical path is free from any optical obstacles like
rubberized fabric, to avoid inaccurate results.
Excessive ambient light may affect the measured results, such as surgical light (especially xenon
light sources), bilirubin lamp, fluorescent lamp, infrared heater and direct sunlight, etc. In order to
