• The default heart rate limit is 200 - age, which is obtained from the personal information you enter.
• If you disable voice guidance for individual workouts, you will only be alerted through vibrations
and card prompts.
• Heart rate alerts are only available during active workouts and are not generated during daily
monitoring.
To enable High heart rate alert for your resting heart rate, open the Health app, touch Devices
then your device, go to Continuous heart rate monitoring > High heart rate alert, and set
your heart rate upper limit. Then, touch OK. When you are not doing any exercise, you will
receive an alert when your resting heart rate stays above your set limit for more than 10 minutes.
Tracking sleep
Your watch collects sleep data and identifies your sleep status when you wear it while sleeping.
It can automatically detect when you fall asleep and wake up and whether you are in a light or
deep sleep. You can sync and view your sleep data in detail in the Health app.
Your watch measures your sleep data from 20:00 to 20:00 on the following day (24 hours in
total). For example, if you sleep for 11 hours from 19:00 to 06:00, your watch will count the
length of time you slept before 20:00 during the first day as well as the rest of the time that you
were asleep during the second day.
From the home screen press the Up button, swipe until you find Sleep, then touch it and swipe
up on the screen to view your nighttime sleep duration and nap duration. Your daytime sleep
duration is displayed under Naps.
You are able to view your history sleep data in the Health app. Open the Health app and touch Sleep
to view your daily, weekly, monthly, and yearly sleep statistics.
Naps that you take during the day are counted under Naps. If you take a midday nap of less than 30
minutes or you moved around too much during a midday nap, your watch may have determined
incorrectly that you were awake.
You can enable TruSleep
TM
in the Health app.
After you enable TruSleep
TM
, your watch will collect your sleep data, detect when you fall asleep,
wake up, and whether you are in a light, deep, or REM sleep, and identify the times when you wake
up and your breathing quality to provide you with a sleep quality analysis and suggestions to help
you understand and improve your sleep quality.
When your watch detects that you are sleeping, it will automatically disable Always-on screen,
message reminders, incoming call notifications, Raise wrist to wake screen, and other features in
order to not disturb your sleep.
