SleepTrak 2.0
The sleep tracker monitors the duration and quality of sleep based on motion,
arm posture and ambient light. It automatically detects the beginning and end
of your sleep session.
For full control, you can also manually operate the feature by double-clicking
START/STOP while in Time.
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 is10 minutes.

Intelligent Wake-Up
Your life tracker includes Intelligent Wake-Up and a gentle vibrating alarm.
This alarm can be set to wake you at your optimal time.
The Intelligent Wake-Up feature can be adjusted in the Alarm setup (under
the “Adjust Alert Start” setting; see p.19).
After setting the alarm time, you have the option
of setting an Intelligent Wake-Up window
(0-59 mins) which will activate prior to the alarm
time. During this window, the vibration alarm
will activate only if you are no longer in a deep
sleep stage.
If you are still in a deep sleep stage during
the Intelligent Wake-Up window, the vibration
alarm will activate at the set alarm time.

Heart Rate
Taking your heart rate will help you stay in your workout zones and help
calculate your calorie burn more accurately.
1. Wear snugly around your wrist.
2. Gently press and hold VIEW for 3 to 8 seconds until your heart rate
appears.
Helpful Hints
If you are having difficulty acquiring your heart rate, try the following:
1. Make sure your life tracker is snugly strapped to your wrist. A loose fit
makes it more difficult to properly measure your heart rate.
2. Upon putting on for the first time, allow a one-minute “warm up”
before trying to acquire your heart rate.
3. When touching the heart sensor button (VIEW), make sure you are
using the soft, flat pads of your fingers, not the tips of your fingers.
4. Touch gently with enough pressure to activate the heart sensor
button (VIEW). Pressing too hard can make it difficult to measure
your heart rate.
5. Make sure the back metal plate is lying flat on your skin.
6. Make sure your wrist and fingers are clean and free from dirt, oils,
or lotions.
