Wearing the Watch
CAUTION
Some users may experience skin irritation after prolonged use of the watch, especially if the user has sensitive
skin or allergies. If you notice any skin irritation, remove the watch and give your skin time to heal. To help
prevent skin irritation, ensure the watch is clean and dry, and do not overtighten the watch on your wrist. For
more information, go to garmin.com/fitandcare.
• Wear the watch above your wrist bone.
NOTE: The watch should be snug but comfortable. For more accurate heart rate readings, the watch should
not shift while running or exercising. For pulse oximeter readings, you should remain motionless.
NOTE: The optical sensor is located on the back of the watch.
