Smart Alarm
The smart alarm uses the watch's
accelerometer and heart rate sensor to
estimate your sleep state and notify you by a
10-second sound or vibration operation when
your sleep is light during a specified period.
For example, if you set an alarm time of 7:30
and a smart period of 60 minutes, the alarm
alerts you to a good time to awake between
the hours of 6:30 and 7:30.
Important!
Make sure you leave the watch affixed
●
to your wrist when using the smart
alarm.
