Wear Charge 3
PlaceCharge 3 around your wrist. If you need to attach a different size wristband,
or if you purchased an accessory wristband, you'll find instructions in "Change the
wristband" on page14.
Placement for all-day wear vs exercise
When you're not exercising, wear Charge 3 a finger's width below your wrist bone.
For optimized heart-rate tracking while exercising, keep these tips in mind:
l Try wearing Charge 3 higher on your wrist during exercise for an improved fit
and more accurate heart-rate reading. Many exercises, such as bike riding or
weight lifting, cause you to bend your wrist frequently, which can interfere
with the heart-rate signal if the tracker is lower on your wrist.
