Heart Rate Features; Wrist-Based Heart Rate; Wearing The Watch; Tips For Erratic Heart Rate Data - Garmin Venu 3 Series Owner's Manual

The Venu 3 series watch has a wrist-based heart rate monitor and is also compatible with chest heart rate
monitors (sold separately). You can view heart rate data on the heart rate glance. If both wrist-based heart rate
and chest heart rate data are available when you start an activity, your watch uses the chest heart rate data.

Wrist-based Heart Rate

Wearing the Watch

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.
