SLEEPTRAK
2.0
Sleep data collection
SleepTrak 2.0 is smart enough to distinguish if the
device is on or off your wrist. Sleep tracking is disabled
when the device is not on your wrist.
Total sleep time is accumulated during all sleep
sessions that end on a particular day. For example, if
you fell asleep last night and woke up this morning, your
sleep duration will be added to today’s total sleep time.
However, if you fell asleep last night at 10:00 p.m. and
woke up at 11:00 p.m., that hour of sleep would be
added to yesterday’s total sleep time.
NOTE: Once you wake up, the total sleep time will
update after a brief period.
NOTE: Minimum sleep time for recorded data is
10 minutes.
