3.2 Second, enter “Main Menu” -> “Record” -> make sure the record mode displays “On”
3.3 Exit and return to measurement interface, now insert your finger deep inside to the oximeter, wait for a few seconds to read your SpO2 & PR. Meanwhile, a red dot will be flashing at the left upper corner, indicating the data is now being recorded.
3.4 The screen will sleep after 90 seconds, you can wake up the screen anytime by pressing the button for 2 seconds. (The infrared light above your fingernail is on even the screen sleeps)

4.5 Once the synchronizing completes, the list of all recordings will be displayed on the app.
Tips: The three bar graphs on each recording gives you the general idea of how your SpO2 & HR do over time.
- Left bar shows the highest & lowest oxygen level over time.
- Middle bar shows the highest & lowest heart rate over time.
- Right bar shows perentage of the SpO2 is above & below the threshold.
- Middle bar shows the highest & lowest heart rate over time.
- Right bar shows perentage of the SpO2 is above & below the threshold.
For example, if all your SpO2 is above 94 (the default threshold) over time, then it will be 100% above and 0% below.
