will not be used any more than 7 days.
The recommended storage environment of the
device:
ambient temperature: -20ºC ~60ºC, relative
humidity 10%~95%, atmospheric pressure:
50kPa~107.4kPa.
The Oximeter is calibrated in the factory
before sale, so there is no need to calibrate it
during its life cycle. Any SpO
2
simulators should
not be used to validate the accuracy of the
Oximeter, they can only be used as functional
testers to verify its precision. The SpO
2
accuracy claimed in this manual is supported
by the clinical study conducted by inducing
hypoxia on healthy, non-smoking, light-to-dark
skinned subjects in an independent research
laboratory
.
If it is necessary to verify the precision of the
Oximeter routinely, the user can do the
verification by means of SpO
2
simulator, or it
can be done by the local third party test house.
Please note that the specific calibration curve
