Heart rate /Spo2/Stress Data Inaccurate
Heart rate /Spo2/Stress monitoring can be affected by various
environmental and situational factors. If you find that your heart rate
measurement is unsuccessful during use, or the data is incorrect, please
refer to the following: 6.2 The Heart rate /Spo2/Stress data is inaccurate
Ensure that the back of the watch is clear of foreign objects that may block the
heart rate monitoring sensor.
Extreme low temperatures may also alter the blood flow of the human body and
cause the heart rate measurement to be inaccurate. In this case, it is
recommended that you initiate a heart rate measurement once you have
warmed up.
Heart rates are much easier to measure during regular movement exercises
(such as running, walking, and riding) compared to irregular movement exercises
(such as basketball and free activities), while wrist strength exercises (such as
weightlifting) may even complicate the process.
If you find that your heart rate is abnormal during an exercise, keep your watch
facing upwards and stand still for approximately 10 to 15 seconds to check
whether your heart rate returns to normal. If your heart rate cannot be
measured after multiple attempts, it is recommended that you restart your
watch and try again.
Sleep Data Inaccurate
This can be caused by wrist or arm movement during sleep, leading your
watch to fail to recognize that you were sleeping, and thus will not record
sleep data. To prevent inaccurate readings, try wearing the watch on your
non-dominant hand while sleeping (on your left hand if you are right-
handed, and vice versa). 6.3 Sleep Data is Missing
If you sleep less than 4 hrs , your watch may not be able to detect this as sleep
time, and will not record this sleep data in this instance.
If the watch is worn too loosely, it may fail to record sleep data. Make sure that
you wear the device correctly.
When you are traveling, and sleeping on when in transit, such as on the metro,
or on a bus or train, the movement of the train or vehicle may affect the
recorded sleep data.
Your watch determines whether it is being worn through a built-in PPG sensor,
which reflects light off your skin. The built-in sensor in the watch usually detects
light reflected from human skin at different wavelengths. When the wearable
device is placed on surfaces such as a desk, sofa, or quilt with the sensor facing
down, light reflected from these surfaces may be similar to that from human
skin. In this case, the watch may think that you are wearing the device, and start
recording sleeping data.
If you turned over or accidentally touched the wearable device screen multiple
times while sleeping, the device may exit Sleep mode and record false wake up
times, based on the detected movements.
If there is minimal movement after waking up, the wearable device may remain
in Sleep mode, and fail to record the actual wake up time.
The accuracy of sleep monitoring is closely related to how you wear the watch
and your wrist movement.
Make sure that you keep the wearable device facing upward and wear it slightly
back on the wrist. Do not wear the wearable device too tight or too loose to
avoid inaccurate sleep data.
When you do not use your wearable device for a while, turn it to its side and
place it on a flat surface to minimize any inaccurate sleep data recorded. Power
off your wearable device if you do not use it for a long time.
How do I Update my watchUpdate my watch
During an update, your watch will automatically disconnect from Bluetooth,
and will reconnect once the update is complete. 8.1 How to update my watch
Method 1: Connect your watch to the phone using the NoiseFit app. Open the
NoiseFit app, go to setings, select noise XFit-1 and then click on check for
update. Follow the onscreen instructions to update your watch.
3. Check the network signal quality of the area where the user is located. The
call signal may be poor if the network connection is not stable. Advise the user
to try making calls in an open area with stable network connection.
