2. Position the watch so there is at least one finger width
between it and your wrist joint when you bend your hand
back.
3. After you determine the best wrist position, tighten the
band snugly so the watch does not slide on your wrist.
Important!
A band that is snugly tightened for heart rate measurement can make it
difficult for air to pass under the band and cause you to sweat, which
can lead to skin irritation. During normal wear, when you do not need to
monitor your heart rate, make sure to maintain enough band looseness
so you can insert a finger between it and your wrist.
Avoid using sunblock, hand cream, cosmetics, and other skin
applications on the wrist where you will wear the watch for heart rate
measurement. Such creams and gels can soil the sensor window of the
watch and reduce heart rate measurement accuracy. Avoid using such
agents on the wrist where you will wear the watch.
