All-day wear and exercise
When you're not exercising, wear SW302A a finger's width above your wrist bone.
For optimized heart-rate tracking while exercising:
· Try wearing SW302A 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 watch is lower on your wrist.
· Make sure the watch is in contact with your skin.
· Don't wear your watch too tight, a tight wristband restricts blood flow, potentially affecting the heart-rate signal. The watch should be slightly tighter (snug but not constricting) during exercise.
With high-intensity interval training or other activities where your wrist is moving vigorously and non-rhythmically, the movement may limit the sensor's ability to provide a heart-rate reading. If your watch doesn't show a heart-rate reading, try relaxing your wrist and staying still briefly.
Remove a wristband
To remove the wristband:
Turn over SW302A and find the quick-release lever.
While pressing the quick-release lever inward, gently pull the wristband away from the watch to release it.
Repeat on the other side.
Attach a wristband
To attach a wristband:
Attach the wristband with the clasp to the top of the watch. Slide the pin (the side opposite the quick-release lever) into the notch on the watch.
While pressing the quick-release lever inward, slide the other end of the wristband into place.
When both ends of the pin are inserted, release the quick-release lever.
