SLEEP TRACKER
For full control, you can also manually

START/ STOP while in Time Mode.

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: The minimum sleep time for recorded
data is 45 minutes.

HEART RATE MONITOR
1. VIA CHEST BELT
The Zone R420 is BLE chest belt compatible (sold separately). This additional
feature lets you record continuous heart rate readings to your watch, so you can
capture complete heart rate and calorie burn data during your workout. To help
you track your results, you can also sync your cardio data to the LifeTrak app after
your workout - so you know if you need to push harder next time.
2. VIA FINGER TOUCH
Don’t want to wear a chest belt, but you want a heart rate reading? Get your
ECG heart rate reading at the press of a button - no chest strap needed!
MEASURE YOUR HEART RATE TWO WAYS
8
Your heart is at the center of everything you do – fueling your life and driving your passions.
Monitoring your heart rate and using it in activity tracking is the most accurate way to set
your tness goals and help you reach them.
Why measure heart rate?
- Taking your heart rate will help you stay in your workout zones and help calculate your
calorie burn more accurately.

CONTINUOUS HEART RATE (BLE CHEST BELT)
Place your compatible* Bluetooth®

breathing.
For optimal results, let the chest belt
‘warm up’ for a few minutes before
starting your workout.

You can get your Maximum Heart Rate (MHR) from a MHR test (consult your doctor),
or you can estimate it using the following formula:
Women Maximum Heart Rate = 226 - age
Men Maximum Heart Rate = 220 - age
Here are some common Heart Rate Zones:
HELPFUL HINTS ABOUT HEART RATE ZONES
WARNING: Before starting a new exercise routine, please consult your doctor or health
care professional to help you determine your maximum heart rate, upper and lower limits,
exercise frequency and duration appropriate for your age, condition and specic goals.
25
Example based on a 35 year old
male
220 - 35 (age) = 185 (MHR)
To calculate the HR ZONES, multiply
185 (MHR) by the percentages to the
left. This will help you determine the
LO and HI levels of each zone.
For a Medium Intensity (Endurance):
185 x 0.7 = 130 (LO) and
185 x 0.8 = 148 (HI)
50% - 60% MHR
60% - 70% MHR
70% - 80% MHR
80% - 90% MHR
90% - 100% MHR

If you are having difculty acquiring your heart rate, try the following:
1. Make sure your LifeTrak tness tracker is snugly strapped to your wrist.
A loose t makes it more difcult to properly measure your heart rate.
2. Upon putting on for the rst 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,
at pads of your ngers, not the tips of your ngers.
4. Touch gently with enough pressure to activate the heart sensor button (VIEW).
Pressing too hard can make it difcult to measure your heart rate.
5. Make sure the back metal plate is lying at on your skin.
6. Make sure your wrist and ngers are clean and free from dirt, oils,
or lotions.
7. Clean the heart sensor button (VIEW) and back metal plate with a mild soap and
water, or similar cleaning solution.
8. Moisten with water the pads of the ngers you are using to contact the heart sensor
button (VIEW).
9. Moisten the surface between the back metal plate and the skin on your wrist with
water.
