Module No. 3515
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.
Note
To use the smart alarm, select [ON] or [ACTIVITY & NIGHT TIME ON] for heart rate measurement to enable continuous heart rate measurement. When [OFF] is selected for heart rate measurement, the smart alarm functions as a normal alarm.
Note that no guarantees how you will feel when you wake up by the smart alarm. Depending on your physical makeup and condition, the watch may not be able to determine your sleep state accurately.
The smart alarm is a function that helps you wake up. It does not improve your sleep quality. To improve your sleep quality, you need to adjust your life rhythm and ensure you get enough sleep.
Sleeping for shorter periods can cause sleep status measurement to be less accurate.
Your sleep state cannot be determined if your sleep time, excluding the alarm time, is less than two hours. The watch performs a sound and/or vibration operation when the alarm time is reached.
You can enable or disable sound and vibration alert as required.
Sound and vibration alert is not performed while the battery indicator is “CHG” or lower.
