Wear Charge 4
PlaceCharge 4 around your wrist. If you need to attach a different size band, or if
you purchased another band, see the instructions in "Change the band" on page13.
Placement for all-day wear vs. exercise
When you're not exercising, wear Charge 4 a finger's width above your wrist bone.
For optimized heart-rate tracking while exercising:
l During a workout, experiment with wearing your tracker a bit higher on your
wrist for an improved fit. Many exercises, such as bike riding or weight lifting,
cause you to bend your wrist frequently, which could interfere with the heart-
rate signal if the tracker is lower on your wrist.
