Date and Time are set automatically when you pair your tracker to your smartphone during the set up process in the app.

To view your blood pressure on your tracker, scroll to the blood pressure page (by tapping the function button). Wait around 25 seconds for your blood pressure readings to appear on your tracker.

If you want to get the readings of BP each hour in the app, please switch the BP monitoring to automatic ( Y39 > Switch setting > BP automatic monitoring – enable)( It will use more battery power).

For calibration of your tracker and to get more accurate tracking result, please enable the BP private mode ( My device > Y39 >BP private mode ) in the App and enter your blood pressure value obtained from medical instrument.

First you need to install the H Band app, enter your personal data including gender, height, weight, age, etc in the App and run through the set up process to pair it to your smartphone. If you walk less than 20 steps within a certain amount of time, these steps will not be stored. This is to help improve accuracy by filtering out movements other than steps, for example driving, typing on a keyboard or washing your hands.

Your tracker will automatically track how long and how well you sleep. Stats of sleep quality can be viewed in the app. Generally, you can read the stats 10-30 minutes after you wake up for data to synchronize with phone.

To view your heart rate, switch to the Heart Rate page. Wait around 2 seconds for your heart rate reading to appear. The beats per minute (BPM) figure will then update every 0.5 seconds. It may take 10-15 seconds for the readings to stabilize. Make sure the heart rate sensor is always in direct contact with your skin of wrist, your tracker should lay flat about one finger’s width away from your wrist bone.
It should be noted that automatic heart rate monitoring happens throughout the day by default. If desired, this option can be switched from automatic to manual-only readings from within the H Band app. This can also help to extend the amount of time between charging. To switch heart rate detection to manual, please set in the app: Mine > Y39 > Switch setting > HR automatic monitoring – turn off.
